PROCEDIMENTO DI SINTESI DI ETERE FLUOROMETILESAFLUOROISOPROPILICO

摘要

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 DEG 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.
