Abstract: PURPOSE: The trifluoromethylketone derivatives supported on silica gel and a producing method thereof are provided to be used as a useful catalyst in the epoxidation reaction using olefin and Oxone oxidizing agent. CONSTITUTION: The trifluoromethylketone derivatives are represented by formula (3), in which R1 is C1 to C6 alkyl, R2, R3 and R4 are individually hydrogen or C1 to C6 alkyl, I is an integer from 0 to 1, m is methylene from 1 to 6, n is an integer from 0 to 2, and O is methylene from 0 to 16. The trifluoromethylketone derivatives of formula (3) supported on silica gel are produced by reacting trifluoromethylketone derivatives of formula (1) with mercaptoalkylsilanized silica gel of formula (2) in the presence of organic solvents such as azobisisobutyronitrile, benzene, toluene, acetonitrile or chloroform.
