1,2-丙二醇、环氧丙烷在催化剂的作用下进行开环聚合反应得中间体，再对中间体采用特殊精馏方式进行组分分离，得到纯度达98％以上的二缩三丙二醇，然后经丙烯酸酯化得高纯TPGDA。系统分析二缩三丙二醇提纯前及提纯后所合成的光固化单体二缩三丙二醇二丙烯酸酯（TPGDA）的酯分布及其在UV涂料应用中的性能差异。

Intermediate was prepared via the ring-opening polymerization in the presence of catalyst and 1,2-propylene glycol and propylene oxide used as raw materials, the intermediate as separated by a special rectifying process, the tripropylene glycol of over 98% purity was obtained. Finally, high purity TPGDA was synthesized by esterifieation with acrylic acid. The ester distribution of tripropylene glycol diacrylate before and after purifying the tripropylene glycol and performance difference in their application of UV coatings was systematic analyzed.
