Abstract

Hexafluoroisopropyl alcohol is prepared by reacting hexafluoroacetone with hydrogen at a temperature of at least 200 DEG C. in the presence of a catalyst comprising metallic copper and chromium oxide. The catalyst may be used on a support, alkaline earth metal fluorides being specified for this purpose. An Example is given.ALSO:A catalyst for the hydrogenation of hexafluoroacetone to hexafluoroisopropyl alcohol (see Division C2) comprises metallic copper and chromium oxide which may be supported on an alkaline earth metal fluoride, preferably calcium fluoride. An example describes the preparation of such a catalyst by addition of an aqueous solution of potassium fluoride and hydroxide to an aqueous solution of copper and chromium nitrates. The precipitate is separated, dried and reduced with hydrogen to give the catalyst.
