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.

本文对基乙酸的工艺进行了比较研究,认为硫氢化钠法和硫代硫酸钠法生产本低,适宜于选矿用基乙酸的生产,而硫脲法到较高浓度的基乙酸。

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.

基乙酸钡和基乙酸钡-钠都能提高PVC的热稳定性,但基乙酸钡的稳定性要好于基乙酸钡-钠。
