Abstract: A catalyst includes a carrier, and a metal obtained by reducing a metal ion supported on the carrier 1) in a supercritical state or 2) in a polar organic solvent, wherein the carrier is an inorganic porous body having a hierarchical porous structure. By employing the catalyst, it is possible to exhibit better catalytic activity than a conventional catalyst. Heat generation and spontaneous ignition are prevented because no organic porous body is used.

Abstract: It is possible to produce an optically active fluoroalkyl chloromethyl alcohol with a high optical purity and a good yield by treating a fluoroalkyl chloromethyl ketone with a microorganism having an activity for asymmetrically reducing the ketone or an enzyme having the activity. Then, it is possible to obtain a fluoroalkyl ethylene oxide by treating the alcohol with a base. Industrial implementation of the production method of the present invention is easy.
