Thioglycolic acid(TGA) was synthesized from thioglycolic acid and sodium hydrosulfide under common pressure.

研究了以氢化氯乙原料常压合成巯基乙。

Using sodium hydrosulphide or sodium thiosulfate as materials,the production cost of TGA is low.While,a high content of TGA can be obtained with thiourea as reactant.

本文对巯基乙合成工艺进行了比较研究,认氢化法代法生产成本低,适宜于选矿用巯基乙生产,而脲法可得到较高浓度巯基乙。

Results indicate that both of barium thioglycolate and barium-natrium thioglycolate can increase the thermal stability of PVC system, and the thermal stability of barium thioglycolate is better.

巯基乙钡巯基乙钡-都能提高PVC热稳定性,但巯基乙钡稳定性要好于巯基乙钡-。
