Method of removing fluorinated olefin byproduct formed during the synthesis of a fluorinated ether

摘要

The method of removing fluorinated olefin byproduct formed during the synthesis of a fluoromethylhexafluoroisopropyl ether product or the like comprises: adding ammonia or an amine to the mixture to react with the fluorinated olefin byproduct, and thereafter distilling the fluoromethylhexafluoroisopropyl ether product to remove it from the byproduct.
