Process for separating 1-chloro-2,2,2-trifluoroethyl-difluoromethyl-ether from its mixture with 1-chloro-2,2,2-trifluoroethyl-difluoro-chloromethyl-ether by distillation.

摘要

Azeotropes of 1-chloro-2,2,2-trifluoroethyl difluoromethyl ether and acetone, methyl ethyl ketone or tetrahydrofuroan are formed and used to separate this ether from 1-chloro-2,2,2-trifluoroethyl difluorochloromethyl ether.
