摘要：
The present invention relates to a catalyst for preparing para-chloro aromatic compounds by the liquid-phase chlorination method. The catalyst is prepared by loading transition metal salts, rare earth metal salts or a mixture thereof, and alkali metal or alkaline earth metal chlorides having a melting point of 300.degree. C. or more, by solid-state method or impregnation method, into zeolite L being ion-exchanged by alkali metal. The present invention also relates to a process for preparing para-isomers of the chlorinated compounds by using the catalyst.
