巯基乙酸

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

了以硫氢化钠和氯酸钠为原料常压合成酸。

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.

本文对酸的合成工艺进行了比较,认为硫氢化钠法和硫代硫酸钠法生产成本低,适宜于选矿用酸的生产,而硫脲法可得到较高浓度的酸。

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.

酸钡和酸钡-钠都能提高PVC的热稳定性,但酸钡的稳定性要好于酸钡-钠。
