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

研究了以硫氢化钠和氯乙钠为原料常压合成乙。

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.

乙钡和乙钡-钠都PVC的热稳定性,但乙钡的稳定性要好于乙钡-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.

本文对乙的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,适宜于选矿用乙的生产,而硫脲法可得到较浓度的乙。
