发明名称 Phenolic ester synthesis
摘要 A process which enhances conversion and speeds the reaction rate for the preparation of esters. Methyl acrylate and a hindered phenol are reacted (i) in the presence of an alkali metal alkaline catalyst that provides a phenolate anion and (ii) in the presence of an agent which solubilizes the phenolate to enhance the reaction rate. Excellent yields of methyl ester are obtained in a rapid reaction and by-products are minimal. The invention includes a preparation of methyl beta -(3,5-dialkyl-4-hydroxyphenyl)propionates by reaction of a hindered phenol with methyl acrylate in the presence of an alkaline catalyst and dimethyl sulfoxide present in an amount sufficient to advance the reaction rate.
