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

研究了以硫氢化钠和氯钠为原料常压巯基。

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.

本文对巯基工艺进行了比较研究,认为硫氢化钠法和硫代硫钠法生产本低,适宜于选矿用巯基生产,而硫脲法可得到较高浓度巯基。

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.

巯基钡和巯基钡-钠都能提高PVC热稳定性,但巯基钡稳定性要好于巯基钡-钠。
