巯基乙酸

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

研究了以化钠和氯乙钠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.

本文对巯基乙的合成工艺进行了比较研究,认化钠法和钠法生产成本低,适宜于选矿用巯基乙的生产,而脲法可得到较高浓度的巯基乙。

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.

巯基乙钡和巯基乙钡-钠都能提高PVC的热稳定性,但巯基乙钡的稳定性要好于巯基乙钡-钠。
