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

研究了化钠和氯乙酸钠为原料常压合成乙酸。

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.

乙酸钡和乙酸钡-钠都能提高PVC的热稳定性,但乙酸钡的稳定性要好乙酸钡-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.

本文对乙酸的合成工艺进行了比较研究,认为化钠法和代酸钠法生产成本低,适宜选矿用乙酸的生产,而脲法可得到较高浓度的乙酸。
