Abstract

PURPOSE: To obtain advantageously the titled compound useful for preparing plastics, etc., by feeding an alcohol as a raw material from the divided parts located to keep proper intervals in the direction of the gas flow of catalytic layer, in reacting a phenol with the alcohol in the presence of the catalyst in gas phase.
CONSTITUTION: A phenol shown by the formula (R1WR4 are H, 1W4C hydrocarbon residue, aromatic hydrocarbon residue, e.g., phenyl, naphthyl, etc. capable of having substituent) is reacted with a 1W4C lower alcohol in the presence of a catalyst, e.g., aluminum oxide-containing catalyst to give the titled compound useful for preparing polyphenylene ether, etc. The alcohol as a raw material is fed from parts located at proper distances in the direction of gas flow of catalytic layer so that the temperature distribution of the catalytic layer is controlled, the production of orthoalkylated phenol per unit catalyst is raised without changing its selectivity, and the effective utilization of the alcohol is extremely improved.
