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

研究了以硫和氯乙酸为原料常压合成巯乙酸。

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.

巯乙酸钡和巯乙酸钡-都能提高PVC的热稳定性,但巯乙酸钡的稳定性巯乙酸钡-。

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.

本文对巯乙酸的合成工艺进行了比较研究,认为硫法和硫代硫酸法生产成本低,适宜选矿用巯乙酸的生产,而硫脲法可得到较高浓度的巯乙酸。
