Fractional Distillation
Title:
Distillation of an Ethanol Using Fractional Distillation Lab Report

Abstract:
This experiment aimed to separate the components of a mixture using Fractional Distillation. A volume of 28.0mL of a mixture including ethanol was heated until the temperature reached
78.0 C. Approximately 1.0mL of distillate was collected between 78.0 – 84.0 C. Percent composition by weight of the 1.0mL sample was determined to be 95% ethanol. By careful and accurate techniques, a high percent composition of ethanol was achieved.

Introduction:
Distillation is the ancient process of separating a liquid into its volatile components by vaporizing a liquid by heating, condensing the vapor by means of a cool condenser, and collecting the condensation thereafter. Distilling is used in many practical ways such as purifying contaminates out of water to obtain clean water for drinking, to produce a variety of alcoholic beverages like vodka or whiskey, refining oils such as the gasoline we put in our cars, to make aromatic perfumes, and in natural food flavorings (Maxfield, 2013.)There are many different ways of distilling, but this experiment uses fractional distillation as the method for extracting ethanol from a mixture. In fractional distillation a column is inserted between the distillation flask and the distilling head. This column is then packed with a stainless-steel sponge. This allows for the mixture to continuously go through many vaporization-condensation cycles while moving up the column. With each cycle the percent composition of the vapor increases. Finally, pure or close to pure ethanol, in this case, condenses and is collected in a receiving container
(Engel, Kriz, Lampman, Pavia, 2011).

    In this experiment, the molecular weight of a condensed vapor was found through a procedure using an unknown liquid. The flask before adding the unknown liquid in was full of air. After the beaker full of water started to boil the flask was examined until the unknown liquid was completely vaporized. At that exact point the flask contained all vapor. At the final weighing the flask contained condensed vapor and air. There is always a chance for error. Some sources of error could have come with completing this lab over an open water bath and some water vapor may have been in place. Also, too much vapor could have escaped and the experiment might not have been stopped quick…

    Objective: The main goal of this lab is to learn how separation of binary liquid mixtures is performed. Especially when the two liquids have boiling points varying by about 30° C. Hexane can be separated from toluene in this experiment because of the difference in their boiling points. Since toluene has a higher boiling point, it will left at the bottom while the hexane starts to boil out and collect in the Hickman still. GC measurements help us in determining how accurate our data is by making a graph of the amount of hexane and toluene in each fraction. Also this lab gives experience with semi-micro distillation in order for experiments in the future that might need this purification setup.…

    About 1.55-g of benzil, 1.51-g of dibenzylketone and 12-mL of ethanol were placed in a 50-mL round bottom flask. A magnetic stir bar was also placed in the flask. A condenser was attached to the round bottom flask while the flask was placed in a 70oC hot water bath. The mixture was heated until all solids were dissolved. The temperature of the water bath was then heated to 80oC. A pasture pipet was used to add 2.25-mL of ethanolic potassium hydroxide solution downward through the condenser and into the flask.…

    The purpose of this experiment was to isolate the aromatic hydroxyl compound, eugenol from crushed cloves using steam distillation. After conducting the distillation, the expected two layers were not visible in the centrifuge tube. Subsequently, the extraction and evaporation did not produce the expected oil. This result is probably due to the collection of only water vapor during distillation.…

    Distillation is a method of separation for homogenous mixtures, which are composed of both volatile and nonvolatile substances [1]. It involves the volatile substance to undergo a phase change from a liquid to a gas, and then back to a liquid. The process required for the mixture to be heated at a certain temperature in order for the volatile substance to evaporate and the nonvolatile substance to remain a liquid. As the volatile substance evaporates, it will pass through a condenser, which transforms it back to a liquid and therefore separates the substance from the original mixture. The principle behind this process is the difference in the boiling points of each of the components of the mixture. Boiling point is the temperature at which a liquid becomes a gas. The nonvolatile substance remained as a liquid because of its high boiling point, allowing the volatile substance, which had a low boiling point, to evaporate.…
