摘　　要：介绍了一种制备三羟甲基丙烷三丙烯酸酯（ＴＭＰＴＡ）的方法──酰氯法。用本法可得纯度＞９９．９％、收率＞９８％的题示产物。原理简单，途径简捷，无需阻聚剂，大大简化了后处理工艺，成本降低。We recommend here a method of efficiently preparing high purity trimethylolpropane triacrylate. Using acrylic acid,thionyl chloride and trimethylolpropane as starting materials. We can make the product with percentage yield of >98% and a purity of>99.9%. The method we used is quit simple. Moreover due to the low reaction temperature,polymerization inhibitor is not needed. It will simplify the purification process,hence will reduce the cost.
