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

研究了以氢化钠和氯乙酸钠原料常巯基乙酸。

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.

本文对巯基乙酸工艺进行了比较研究,氢化钠法和代酸钠法生产本低,适宜于选矿用巯基乙酸生产,而脲法可得到较高浓度巯基乙酸。

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.

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