    摘要: A continuous process for producing methacrylic acid ester from methacrylic acid and a lower alcohol containing 1 to 3 carbon atoms utilizing sulfuric acid as a catalyst and a hydrophobic solvent to assist in the formation of a heterogeneous reaction mixture, the process being particularly characterized by the steps of reconcentrating and reusing the sulfuric acid.
