摘要
研究了巯基乙酸酯化反应的催化剂,采用一种新型的有机酸作催化剂与国外常用的无机酸比较,具有实验步骤简单、产率高的特点。以自制的巯基乙酸乙酯与三氧化二锑反应首次合成了三(巯基乙酸乙酯)锑。对产品进行了红外光谱分析及各项理化指标的测试,研究了其在PVC塑料中的热稳定性能。
Various catalyst's effect on the synthesis of ethylthioglycollate has been studied system-atically. A new type of organic acid has been used as catalyst to increase productivity andsimplify experiment procedures. Antimony tri (ethylthioglycollate) is synthesized for thefirst time and some physical and chemical data are reported. It was put into PVC plasticproducts and applicable test was made.
