PRODUCTION METHOD OF HEXAFLUOROISOPROPANOL

摘要

PROBLEM TO BE SOLVED: To provide a method for obtaining hexafluoroisopropanol from hexafluoroacetone as a raw material in a sufficiently satisfactory yield from an industrial viewpoint which can be carried out at relatively low pressure at a relatively low temperature and permits simplification of a purification step because the product essentially contains no excessively hydrogenated by-products.

SOLUTION: The production method of hexafluoroisopropanol comprises hydrogenating hexafluoroacetone by bringing it into contact with a hydrogen gas at -20 to 60°C in a hydrogen fluoride solvent in the presence of a metal catalyst such as palladium or ruthenium or a catalyst comprising the metal catalyst carried on a carrier.
