The purpose of this experiment is to observe what happens when two liquids with a boiling point of 79 and degrees centigrade are heated together and allowed to boil over a specific period, to use the density to determine regenerate composition of ethanol and water and also to understand the process to separating a solution with different boiling points.

Distillation deals with a mixture of liquids with different boiling points. This is because every element has a unique boiling point due to the amount of bonds and structure of that fluid. Hence, understanding the structure and bonds of a fluid gives us more glimpse of what their densities may look like. There normal boiling point is 79 and OIC degree centigrade respectively. Therefore, as the solutions get heated in the apparatus, the temperature begins to rise.

The ethanol, Which has a lower boiling point than water Will vaporize and condensing into a liquid, which is collected in a beaker through temperature exchange in the condenser.

H 3 boiling chips We assembled the distillation apparatus as shown in the lab manual. We added 3 boiling chips to ensure the formation of bubbles and we noted the temperature we obtained our first drop. We used a clamp to hold the stopper fitting the probe into the flask in place and we slowly turned on he cold water tap We used a third utility clamp to secure the temperature probe wire We obtained 3 ml beakers which were labeled BBC and beaker A was placed at the end of the condenser and our hot plate was turned to it maximum setting.

When ml was collected in beaker one, we removed it and placed beaker 2 and the same comic was collected for beaker 3. We determine and recorded the mass of ethanol obtained during our experiment. In the distillation process, Mimi Of water and ml of ethanol was collected together however; only Mil was collected meaning that since ethanol has a lower boiling point than water, most of the liquid obtained could be assumed to be ethanol especially during the first two fractions of the experiment.

Also in this experiment, the amount of ethanol collected is in close relation to the temperature of the heated solution. This error occurred as a result of increase in the boiling point, which increased from degree ethanol to degree Celsius water. This error could be controlled by reheating the solution continuously until the percentage of water is greatly reduce According to our observation, the temperature at, which eve experienced our first drop was 73 degree integrate and the boiling point of water in this experiment Vass found to be 89 degree Celsius because the water is diluted water.

Isolation of Acetyleugenol Clove Oil from Cloves Purpose In this experiment, you will obtain the essential oil from cloves by steam distillation. You will then separate a component acetyleugenol from the oil by liquid-liquid extraction. Finally, you will isolate the acetyleugenol by using a rotovap for reduced pressure distillation, which will remove the organic solvent dichloromethane.

Fractional Distillation and Gas Chromatography Lab Report Introduction: Distillation is a method of separating two volatile chemicals on the basis of their differing boiling points.

During this lab, students were given 30 mL of an unknown solution containing two colorless chemicals. Because the chemicals may have had a relatively close boiling point, we had to employ a fractional distillation over a simple distillation. By adding a fractionating column between the boiling flask and the condenser. The objectives of the experiment was to separate the two components of a binary mixture through simple and fractional distillation, to show the concept of simple and fractional distillation and to demonstrate its proper techniques.

For both types of distillation, a mixture. The process of washing the solutions by phase transfer was used in order to remove impurities from the main solvent layer. Finally, the crude product was dried with anhydrous Calcium chloride and purified once more by simple distillation technique.

The first experiment was done on a compound which is commonly known as a triglyceride which contains three fatty acids and a glycerol backbone. The next experiment was done one a caffeine which is a hetercylic ring. However, this. Tan, Joshua Michael L. Torres, Pauleen Anne S. Vanadero, Paulene Arielle P. Ynzon and Rachel Pauline E.

There are four kind of distillation: simple distillation, fractional distillation, vacuum distillation and steam distillation. Simple distillation is the process wherein the pure liquid is separated from the solution with different boiling points.

Boiling chips were placed inside the pear-shaped distilling flask in order to avoid bumping of molecules and prevention of having a contamination. Alcohol lamp was used as the heat source. The group rotated it under the pear-shaped distilling flask in order for the liquid mixture to boil.

Siavosh Naji-Talakar. Simple distillation, used when two liquids have a large difference in boiling point, requires boiling a liquid in a flask and channeling the vapors through a cooling apparatus where the vapors will be converted back into a pure liquid that flows down a collection duct.

Simple distillation experimental results indicate that acetone has a boiling Acetone - C3H6O point of Fractional distillation is similar to simple distillation but differs in that a fractionating column is used to allow for successive condensations and distillations which produce a better separation between liquids that have a small difference in boiling point Williamson, Fractional distillation experimental results indicate that acetone has a boiling point of Scientist may use distillation as a tool to identify an organic compound as well as purify it.

Detecting the boiling point of a compound is one of the physical properties used to identify the compound. To purify a compound distillation is used to separate it from a less volatile material. When unlike compounds with different boiling points are in a mixture with each having different boiling points they separate into individual compounds when distilled. In the process of simple distillation a liquid mixture is boiled in a distilling flask.

The resulting vapors from the first compound, with a lower boiling point than the second, are directed through a condenser where the vapors are cooled. These cooled vapors are converted back to their pure liquid state and flow down the condenser into a collecting flask Williamson, Boiling point for the first compound may be identified by the temperature in which the vapors began to condense and flow into the collecting flask.

The remaining liquid from the second compound may be heated still until it begins to boil. The boiling point of the second liquid may be identified when it begins to condense and flow into the collecting flask.

Fractional distillation follows the same principle idea of a simple distillation but differs in that a fractionating column is placed between the distilling flask and the condenser Williamson, Within the fractionating column the escaping vapors interact with packed material, such as copper sponge, and are condensed and are distilled several times as they ascend to the condenser at the top of the apparatus.

This energy is not enough to re- vaporize the higher boiling point liquid but it is enough to energy to re-vaporize the liquid with a lower boiling point that comes in contact with the copper sponge.

This reaction causes the vapor from the lower boiling point liquid to move up while the higher boiling point component moves down Williamson, This successive condensation-vaporization cycle is called a theoretical plate and produces vapor that is more concentrated in the lower boiling point component Williamson, Based on the information regarding distillation, both simple and fraction, we may predict the following.

Mixtures of two compounds with large differences in boiling points may be distilled via simple distillation in order to separate them into pure compounds. The boiling point of each of the compounds may be identified at the point in which the vapor has condensed and begins to flow into a receiving flask.

Compounds that are mixed and each have very close boiling point to one another may be distilled using fractional distillation. Fractional distillation uses successive vaporizing and condensing steps though a fractionating column to give a richer more concentrated vapor in order to allow these two liquids to separate and purify. Again, the boiling point may be identified by observing the point in which the liquid cools and begins to run into the receiving flask.

Assembly of the experimental unit began with four boiling chips dropped into the 15 ml round flask. The flask was filled with 5 ml acetone and 5 ml H Thermometer needle was first inserted into the rubber septum which was in turn placed on top of the distillation head. The rubber stopper of the septum was then flipped over to create a secure and tight connection between the septum, thermometer, and distillation head.

Distillation head unit was connected to the round flask using a connection unit. The entire apparatus was placed inside the sand dish which was on top of the hot plate.Objective: To purify and concentrate a fermentation mixture by both simple and fractional distillation. Density: 0. Transfer the 30 mL of distillate to a mL r.

Set up for the fractional distillation by adding a fractionating column between the r. Drawing of set up below. When the mixture boils, a ring condensate vapor will slowly move up the fractionating column, and the distillate should start to collect. Record the temperature at every 1 mL in the receiving flask. Calculate the density of each fraction. As the yeast cells died and the fermentation process stopped, to make a more concentrated substance, the fermented solution was purified by both simple and fractional distillation techniques.

As the fermentation solution is heated to a boil, some of the lower boiling compound, ethanol, escapes into the vapor phase and is condensed again to the liquid phase before collecting into the receiving flask. The rate of collection in the receiving flask was about drops per second. The distillation continued until about 30 mL of distillate had collected. The density calculation revealed that the new ethanol concentration was about The fractional distillation can further increase the ethanol concentration of the distillate.

In the fractional distillation set-up, a fractionating column, filled with glass beads, is placed between the distilling flask, and the three-way adapter.

The purpose of the column is to provide additional surface area for the separation of the compounds to occur. The different intervals of the column can be thought of theoretical plates. As the solution boils and vapor enters the column, some will condense upon contact with the glass beads into the distilling flask.

The place should reach a state of equilibrium between the vapor and liquid phase for the most effective separation of ethanol from water. Only the compound with the lowest boiling point, ethanol, will reach the top of the column in the vapor phase and become re-condensed in the cooled condenser.

Therefore, impossible to completely isolate the ethanol. Because of time constraints for the fractional distillation not much mL were able to be collected. Also, due to unfortunate circumstances fraction 3 water was contaminated by water pressure drop causing hose to spray water into fraction 3. The difference between the ethanol concentration of the simple distillation product and the first fraction product shows how the fractional distillation was able to increase the ethanol concentration significantly through the use of the column.

The fractional distillation was more time consuming than the simple, but provided a more concentrated product. As more ethanol collected in the receiving flask and water remained in distilling flask, the overall distillation temperature would increase before leveling out.The binary distillation of ethanol and water is made possible due to the difference in volatilities of the components in the boiling liquid mixture.

In this experiment, a continuous distillation unit consisting of a perforated-tray column filled with packing of IMTP 15 together with a partial reboiler and a total condenser. In the experiment, all the feed, distillate, bottom, and reflux flow-meters were calibrated, taking into consideration that the flow meters provide accurate measurements only for water flows.

The refractometer was calibrated to enable the determination of the concentration of ethanol in any given ethanol and water mixture from the refractive index. The relationship between the density of the mixture and the composition of ethanol is no longer linear once it reaches higher concentration. The experiment was done by varying the reflux ratio at 6. Then we kept the reflux ratio at 6. The actual number of stages of the column used in the lab is 5 stages. To find the number of theoretical stages required for the stage, the results from the distillation process was analyzed using the McCabe-Thiele method.

Once up-scaling calculation was done, we used the new theoretical number of stages to run a simulation in Aspen for the binary distillation process. Data from the experiment were used as process conditions to find the heat duty of both the reboiler and the condenser. When the reflux ratio was set to be 6.

This high purity gain might be due to the small amount of the distillate produced. This occurred because it was difficult to maintain the flow rate of the distillate at the specified value gained from Aspen. The data from the experiment shows that the optimum specification for the process is to have the feed enter the column from the middle and a reflux ratio of 7. Even though a higher mole fraction of ethanol was obtained when the feed was at the bottom, the amount of distillate produced was lower compared to the one when it is fed in the middle.

With this, the cost is saved, where we have a smaller amount of feed needed to produce the same amount of the beverage. In conclusion, a higher reflux ratio results in a higher production rate, and the optimum stage feed is at the middle of the column. The distillation column was calculated to be Calibration curve for the 4 flow-meters and refractometer. Distillate Calibration Curve. Sensitive Analysis on RR 0.

Data and Conclusions: The purpose of this experiment was to learn how to use distillation and gas chromatography to separate and identify different compounds from a given mixture. There are several kinds of distillation methods. However, the method that we used in this experiment was fractional distillation.

If the boiling points are too close, this method will not work because the two compounds will begin evaporating at close temperatures and will condense down to the receiving flasks at relatively the same times. This will not create an ideal separation. The apparatus used for this type of distillation is longer than that of a simple distillation experiment because this kind of apparatus creates more efficient separation.

This happens because the fractional distillation apparatus is longer, and allows for several simple distillations to occur within the column itself to more accurately separate liquids.

The inside of the column is said to have theoretical plates, or equilibrium stages that are created by the vapor and liquid stages of a compound that create this accuracy. The column must also be insulated with cotton and aluminum to prevent any heat loss that may lead to inaccurate temperature readings or even effect the Tan, Joshua Michael L.

Torres, Pauleen Anne S. Vanadero, Paulene Arielle P. Ynzon and Rachel Pauline E. There are four kind of distillation : simple distillationfractional distillationvacuum distillation and steam distillation. Simple distillation is the process wherein the pure liquid is separated from the solution with different boiling points. The pure liquid turned into a vapor and left the distilling flask. The vapor then was condensed in the condenser and turned into a distillate. The distillate was collected in a calibrated and numbered test tubes and the temperature was recorded as well.

The group was able to acquire Distillation Objective: To illustrate the use of distillation for separating a mixture of two volatile liquids with different boiling points. Background: Distillation consists of heating a liquid until it vaporizes, and then condensing the vapor and collecting it in a separate container.

Distillation is used to separate mixtures of liquids that either have different boiling points, or that have one component that does not distill. There are many types of distillationeach of which has a distinct purpose.

Steam distillation is used to isolate volatile substances that have high boiling points. When two immiscible liquids are distilled together, the amounts of each component in the distillate are constant. Also, the boiling point of the mixture is lower than that of either of the individual components. Once the liquid mixture is heated to its boiling point, the liquid is converted to vapor.

The vapors, richer in a more volatile component, are then condensed into a separate In this experiment, the distillations of cyclohexane and toluene mixture were carried out. The purpose of this experiment is to compare the efficiency of simple distillation versus fractional distillation for separation of a mixture of toluene and cyclohexane. The mixture was first separated using simple distillation.

A simple distillation apparatus was set up and a Thermowell heater containing sand will also be used as the heat source.These methods separate miscible liquids by utilizing their differences in boiling point.

Simple distillation is great for separating liquids with very large differences in boiling points while fractional distillation is better at separating liquids with closer boiling points. We applied heat with a heating mantle to both flasks and watched the mixture come to a boil.

Then we lowered the heat. Two people took data on the temperature and the amount of distillate collected. They measured this using a 10ml-graduated cylinder, which they emptied when it was full. We collected distillate until we had successive temperature readings around boiling point of water degrees Celsius. The simple distillation was very slow. There was no large jump in temperature difference during the distillation. The fractional distillation did have a large jump in temperature once we had collected about 5 mL of distillate.

We did collect some water as part of out distillation because we let the distillation continue until we hit the boiling point of water. The fractional distillation was more accurate because it allowed the condensation and vaporization of the liquid many times in the fractioning column, which provides a more pure distillate.
