Boiling points of several liquids
benzene 80.2 C
ethyl alcolhol 78.4 C
chloroform 61.3 C
carbon disulfide 46.3 C
Do you think a good seperation of a mixture of ethyl alcohol and benzene could be achieved by distilation?

Yes, you could achieve a good separation, but due to the fact that the difference in boiling points is only 1.8 degrees, chances are you will lose some of the benzine as well.
Controlling the temperature would be key.

My first answer is yes. It seems that one can separate the two, using a fractionating column or a spinning band column.
My second answer is to ask whether there is an azeotropic mixture that you have not revealed, which means that alcohol and benzene can never be completely separated. This I do not know.
My third answer is that there is a tertiary azeotrope of benzene, alcohol, and water. If you distil that way, you can separate alcohol from water, and separate benzene from water.
