The invention relates to a process for producing 1,1,3,3-tetrachloro-1,3-difluoroacetone. This process includes fluorinating hexachloroacetone in a liquid phase by hydrogen fluoride in the presence of a catalyst containing a metal compound. This metal compound can be selected from tin halides, titanium halides, molybdenum halides, tungsten halides, niobium halides, tantalum halides, and iron halides. This process is suitable for producing 1,1,3,3-tetrachloro-1,3-difluoroacetone in an industrial scale.
