PURPOSE:To stably obtain the aimed compound in a high yield by using nickel- containing crystalline metallosilicate as a catalyst in transformation of a halogenated aromatic compound to phenols with hydrolyzing in a vapor phase. CONSTITUTION:A halogenated aromatic compound is hydrolyzed in a vapor phase using nickel-containing crystalline metallosilicate molded preferably by low-acidic binder, especially silica as a catalyst to stably obtain phenols in a high yield using the above-mentioned catalyst generating extremely slighter loss of an active component during reaction as compared with a connectional copper-based catalyst. Besides, said catalyst has a structure resemble to ZSM-5, ZSM-11 or AZ-1 and contains Al and B as metal components preferably having a molar ratio of Si to the metal components of >=10, especially 15-500. Further, a containing amount of Ni is 0.01-20wt.%, preferably 0.01-10wt.% and especially 0.2-5wt.%. |
