Microwave Assist Synthesis Methyl Ferulate through a Cationic Exchange Resin Catalysis Routine

Abstract

Methyl ferulate was synthesized by methanol and ferulic acid with strongly acidic cation exchange resin as catalyst under microwave irradiation. The effect of catalyst activity was investigate by single factor experiment. Amount of catalyst, microwave treatment time, microwave output power and methanlo/ ferulic acid ratio were investigate by single factor experiment and orthogonal experiments. The optimal reaction conditions were ferulic acid being 0.1mol, molar radio of ethanol to ferulic acid being 5:1, mass percent of resin being 30％ of the reagent, microwave power being 300W, reaction time being 25 min. The yield of product was 81.2％ under the potimal conditions. The catalytic characteristics of regenerated catalyst were stable and the yield of product may keep greater than 76% after the 732# resin used five times.
