  摘要：

  提供的是一种顺式二(C4-C20)烷基环己烷-1,4-二羧酸酯，具有优异的PVC树脂增塑性能。使用60%或更多的顺式二甲基环己烷-1,4-二羧酸酯作为起始材料，而不是基于邻苯二甲酸酯或对苯二甲酸酯的芳香酯衍生物。将60%或更多的顺式二甲基环己烷-1,4-二羧酸酯与(C4-C20)一级醇进行酯交换反应，制备60%或更多的顺式二(C4-C20)烷基环己烷-1,4-二羧酸酯。在酯交换反应期间产生的甲醇作为副产物被去除，蒸发的一些一级醇被回收利用。因此制备的60%或更多的顺式二(C4-C20)烷基环己烷-1,4-二羧酸酯表现出优异的增塑特性，包括良好的PVC树脂增塑效率，高吸收率，凝胶后良好的产品透明度，长期使用时表面出血较少等特点。

  Provided is a method for preparing 60% or more cis-di(C4-C20)alkyl cyclohexane-1,4-dicarboxy-late which exhibits superior plasticizing property for PVC resin. Instead of a phthalate- or terephthalate-based aromatic ester derivative, 60% or more cis-dimethyl cyclo-hexane-1,4-dicarboxylate is used as a starting material. The 60% or more cis-dimethyl cyclohexane-1,4-dicarboxylate is subjected to transesterification with (C4-C20) primary alcohol to prepare 60% or more cis-di(C4-C20)alkyl cyclohexane-1,4-dicarboxylate. Methanol produced as a byproduct during the transesterification is removed and some of the primary alcohol, which is evaporated, is recycled. Thus prepared 60% or more cis-di(C4-C20)alkyl cyclohexane-1,4-dicarboxylate exhibits superior plasticizer characteristics, including good plasticizing efficiency for PVC resin, high absorption rate, good product transparency after gelling, less bleeding toward the surface upon long-term use, and the like.
