| titleOfInvention | A catalyst for orthoalkylation of phenols, a precursor thereof, and a method for producing orthoalkylated phenols using such a catalyst. |
| abstract | (57) [Abstract] [Objective] A catalyst having high selectivity and improved lifetime in a gas phase orthoalkylation reaction of phenols using alkyl alcohols as alkylating agents, precursors therefor, and such Another object of the present invention is to provide a method for producing an orthoalkylated phenol, preferably an orthomethylated phenol, using a catalyst. The precursor of the catalyst for orthoalkylation of phenols according to the present invention comprises (a) manganese oxalate, (b) phenol resin fine particles, and (c) at least one selected from basic magnesium carbonate and magnesium oxide. It consists of a dry mixture with a magnesium compound, which can be calcined to obtain the catalyst. Further, according to the present invention, By subjecting an alkyl alcohol and a phenol to a gas phase reaction in the presence of such an alkylation catalyst, the desired orthoalkylated phenol can be obtained with high selectivity. |
