Separation of mesitylene from 1,2,4-trimetyhlbenzene by azeotropic distillation

摘要

Mesitylene is difficult to separate from 1,2,4- Trimethylbenzene because of the proximity of their boiling points. They are readily separated by azeotropic distillation. Effective agents are isopropyl acetate, 2-pentanol and acetonitrile.
