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.

本基乙酸的合成工艺进行比较研究,认为氢化钠法和酸钠法生产成本,适宜于选矿用基乙酸的生产,而脲法可得到较高浓度的基乙酸。

This paper discusses the influence on the oxidation number of each sulfur atom when the charge possesses different position in thiosulfate,polythionate and so on.
