A METHOD FOR PRODUCING 2,6-DIMETHYLPHENOL BY METHYLATION OF PHENOL

摘要

The present invention relates to a methylation catalyst of phenol and a process for producing 2,6-dimethylphenol under the catalyst, useful for producing 2,6-dimethylphenol by reacting phenol and methanol in a gas phase on a fixed bed catalyst. More specifically, in the production of 2,6-dimethylphenol from phenol, the maximal suppression of by-products of alkylphenol compounds substituted with alkyl groups at meta or para positions of phenols such as meta-cresol, para-cresol and 2,4-dimethylphenol And a highly selective ortho-regioselective alkylation catalyst which is excellent in activity and long term reaction stability and a process for preparing 2,6-dimethylphenol under said catalyst.
