ABSTRACT:
Hydroxyaromatic compounds such as phenol are alkylated with alkanols such as methanol in the presence of a catalyst comprising an intimate blend of magnesium oxide and copper, the latter being present in an amount up to about 2% by weight, based on said magnesium oxide. The catalyst is prepared by blending a magnesium reagent and copper in elemental or (preferably) chemically combined form and calcining the same at a temperature within the range of about 350.degree.-550.degree. C. The catalyst promotes ortho-alkylation of the hydroxyaromatic compound in high yield, minimizes decomposition of the alkanol, and has long life.
