Abstract: A transesterification process produces a (meth)acrylate ester product from a mixture comprising an alkyl(meth)acrylate reactant, an alcohol reactant, a catalyst, and a polymerization inhibitor, wherein the water content in the reaction zone at the start of the transesterification step is from 0.2 to 1.1 weight percent, based on the weight of the materials in the reaction zone. The mixture is subjected to reaction conditions sufficient to produce a product (meth)acrylate and a product alcohol, which are different than the reactants.

Abstract translation: 酯交换方法由包含（甲基）丙烯酸烷基酯反应物，醇反应物，催化剂和阻聚剂的混合物产生（甲基）丙烯酸酯产物，其中在酯交换步骤开始时反应区中的水含量 基于反应区中材料的重量，为0.2-1.1重量％。 使混合物经受足以产生与反应物不同的产物（甲基）丙烯酸酯和产物醇的反应条件。
