巯基乙酸

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酸钠为原料常压合成巯基乙酸。

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.

巯基乙酸合成工艺进行了比较研究,认为硫氢化钠法和硫代硫酸钠法成低,适宜于选矿用巯基乙酸,而硫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。
