Abstract
A method of synthesizing fluoromethylhexafluoroisopropyl ether comprises adding hexafluoroisopropyl alcohol to a mixture comprising a stoichiometric excess of paraformaldehyde and hydrogen fluoride, plus sufficient sulfuric acid to sequester most of the water produced by the reaction. The mixture is maintained at a temperature of at least 57.degree. C., to cause vapor formation by boiling of the fluoromethylhexafluoroisopropyl ether formed. The vapor is then collected and condensed, and may be purified by distillation.
