PURPOSE:To prepare the titled compound useful as an industrial raw material, in high activity and ortho-selectivity, at low reaction temperature, by methylating a phenolic compound with methanol using a catalyst containing iron oxide, indium oxide, and chromium oxide. CONSTITUTION:An ortho-methylated phenolic compound is prepared by the vapor-phase catalytic reaction of a phenolic compound having at least one H atom at ortho position with methanol in the presence of a catalyst containing an ion oxide such as Fe2O3, Fe3O4, FeO, etc., an indium oxide such as In2O3, InO, etc.m and a chrominum oxide such as CrO, Cr2O3, CrO2, CrO3, etc. The atomic ratios of Fe:In:Cr in the catalyst are pref. 100:(0.5-50):(0.05-20), more pref. 100: (1- 30):(0.3-10). EFFECT:The methanol utilization is also high. |
