ABSTRACT:
A process for isomerizing trichlorobenzene is disclosed. In the process of the present invention, a mixture of trichlorobenzene isomers containing 1,3,5-trichlorobenzene and/or 1,2,3-trichlorobenzene in small concentrations is contacted with a catalyst including acid type mordenite zeolite or acid type beta zeolite and a rhenium component and/or silver component in liquid phase in the presence of hydrogen, thereby increasing concentrations of 1,3,5-trichlorobenzene and/or 1,2,3-trichlorobenzene in said mixture.
