The invention relates to a process for producing 1,1,1-trifluoroacetone, which is useful as an intermediate of pharmaceuticals and agricultural chemicals, or as a reagent for introducing fluorine-containing groups. This process includes the step of conducting a hydrogenolysis of a halogenated trifluoroacetone, which is represented by the formula [1], by a hydrogen gas, in a liquid phase containing water, in the presence of a catalyst containing a transition metal, where X represents a chlorine, bromine or iodine, and n represents an integer from 1 to 3. It is possible by the process to easily produce 1,1,1-trifluoroacetone with high purity.
