Question

Experiment Design

You are asked to separate a mixture of toluene and cyclohexane. Assume that they do not form an azeotropic mixture. Design an experiment to do this. You must provide the following information.

a) A diagram of the equipment you will be.

b) What distillate fractions you will collect and the temperature range over which you estimate you will collect them.

c) A diagram graph you are expecting of the distillation temp. (y) versus the mass distilled (x), marking on this diagram the point at which you will be collecting each fraction.

d) how you will estimate the efficiency of your recovery of each component.


Thank you so much!

Answer 1

We can't draw diagrams (graphs or equipment set up) on this forum but here is a site that goes into this in detail. This is only one of many; if you don't find something here go to Google and type in "separation toluene and cyclohexane by distillation" without the quotation marks. There is a lot of info on this topic available on the internet.
