Simple Distillation: Separation of Hexane and Toluene

Simple Distillation: Separation of Hexane and Toluene By: Jessica Hauger Abstract: The purpose of this experiment is to separate a mixture of hexane and toluene by collecting fractions through simple distillation. Because hexane’s boiling point is about 69°C and the boiling point of toluene is 111°C, the two compounds distill at different times. The distillation took place in a simple distilling apparatus. The refractive index was measured using an Abbé refractometer. After collecting only two fractions and recording the refractive […]

Simple and Fractional Distillation Experiment

Distillation By: Tim Dimond Introduction/Purpose The purpose of this lab was to purify an unknown mixture of acetone/water by both fractional and simple distillation. This process is a viable method for separation of these two liquids because of the large separation in their boiling points. Material -Water and acetone mixture Equipment – A setup for fractional distillation and simple distillation -100 mL round bottom flask -Volume measuring equipment -Heating equipment Procedure Obtain 70 mL of the acetone/water solution in a […]

Synthesis of Ethanol by Simple and Fractional Distillation

Written by Aarti Prabhu Objective: To purify and concentrate a fermentation mixture by both simple and fractional distillation Procedure Observations 1.) Add 5 g of Celite to the fermentation mixture, mix thoroughly, and then vacuum filter into a large filter flask. Material had settled in the r.b. Flask, but dissolved again when mixed with the Celite. The mixture had a brownish white tint. After filtering, the solution looked yellow and smelt like alcohol. 2.) Transfer the filtered solution back to […]
