有机锑高效PVC热稳定剂的合成

Synthesis of High Efficient Stabilizer for PVC

为开发有机锑类高效PVC热稳定剂，以三氧化二锑与自制的十二烷基硫酸为原料，合成了三（十二烷基硫醇）锑，产率可达87．8％；以三氧化二锑与自制的流基乙酸异辛酯为原料，合成了三（巯基乙酸异辛酯）锑，产率可达93．8％，通过正交实验对反应条件进行了优化。对两产物中间产品进行了分析鉴定，结果与文献值相符。

In order to develop high efficient organic antimony stabilizer for PVC, Antimony tri(n-dodecanethiol) was prepared by using dodecyl alcohol and antimony trioxide as materials, the yield is 87. 8 %, Antimony tri (isooctyl - thioglycalate) was prepared by using thioglycolic acid isooctylester and antimony trioxide as materials The yield reaches 93. 8%. The process was optimized by orthogonal experiments, and the immediates were detected, the results agree with published values.
