发明名称 Separation of cumene from 3-ethyl toluene by azeotropic distillation
摘要 Cumene cannot be separated from 3-ethyl toulene by distillation because of the proximity of their boiling points. They are readily separated by azeotropic distillation. Effective agents are methyl salicylate, diethylene glycol butyl ether and 3-nitrotoluene.
