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.
本发明涉及一种生产1,1,1-三氟丙酮的方法,该方法可用作制药和农业化学品的中间体,或用作引入含氟基团的试剂。该方法包括在含水液相中,在存在过渡金属催化剂的情况下,通过氢气对由式(1)表示的卤代三氟丙酮进行氢解反应,其中X代表氯、溴或碘,n为1至3的整数。该方法能够轻松地生产高纯度的1,1,1-三氟丙酮。
