Purification of fluorinated dimethyl ethers

摘要

A process for the purification of bis(difluoromethyl)ether. Bis(difluoromethyl)ether is exposed to molecular sieves in order to reduce or completely remove impurities. In a further embodiment, the present invention optionally includes means for preferentially inhibiting the formation of CF2HOCCl3 in the formation of bis(difluoromethyl)ether prior to exposing the bis(difluoromethyl)ether to the molecular sieves.
