Experimental justification of the effectivity of the separating power of solvents for extractive distillation of the propylene oxide-methanol binary system

摘要

Highly selective protic and aprotic solvents were compared in terms of their effectivity as extractive distillation agents for the propylene oxide-methanol system. Separating agents were chosen on the basis of their solubility data. A relationship between the capacity of the separating agent and the degree of extraction of propylene oxide was established.
