SEPARATING 1-CHLORO-2,2,2-TRIFLUORO-ETHYL DIFLUOROMETHYL ETHER FROM 1-CHLORO-2,2,2-TRIFLUOROETHYL DIFLUOROCHLORO-METHYL ETHER BY AZEOTROPIC 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.
