巯基乙酸

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

研究了以钠和氯钠为原料常压合成巯。

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.

本文对巯的合成工艺进行了比较研究,认为钠法和代钠法生产成本低,适宜于选矿用巯的生产,而脲法可得到较高浓度的巯。

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.

巯钡和巯钡-钠都能提高PVC的热稳定性,但巯钡的稳定性要好于巯钡-钠。
