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合成巯。

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PVC稳定性,但巯钡稳定性要好于巯钡-钠。

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.

本文对巯合成工艺进行了比较研究,认为硫氢化钠法和硫代硫钠法生产成本低,适宜于选矿用巯生产,而硫脲法可得到较浓度巯。
