CATALYST FOR ORTHO-ALKYLATION OF PHENOLS, A PRECURSOR THEREOF, AND PRODUCTION OF ORTHO-ALKYLATED PHENOLS BY USE OF SAID CATALYST

摘要

There is disclosed a catalyst for ortho-alkylation of phenols obtained by calcination of a catalyst precursor comprising a dry mixture of: (a) manganese oxalate; (b) phenolic resin fine particles; and (c) at least one magnesium compound selected from the group consisting of basic magnesium carbonate and magnesium hydroxide. There is further disclosed a process for producing ortho-alkylated phenols by the gas phase reaction between an alkyl alcohol and a phenol in the presence of the ortho-alkylation catalyst defined above.
