ABSTRACT:
Acetone cannot be easily separated from benzene in high purity by distillation because of the closeness of their vapor pressures. Acetone can be readily removed from benzene by azeotropic distillation using certain aromatic hydrocarbons. Typical effective azeotropic distillation agents are: toluene, ethyl benzene and mesitylene.
