METHOD FOR PRODUCING ORTHO-ALKYLATED PHENOLS

摘要

A method for producing ortho-alkylated phenols comprising reacting phenols represented by the general formula (1) with monohydric or dihydric alcohol in the presence of germanium oxide under conditions in which said alcohol is in the supercritical condition, wherein each of R1, R2, R3, R4 and R5 independently represents a hydrogen atom, or a linear or branched alkyl group having 1 to 10 carbon atoms.
