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.

本文讨论了、多酸根等中所带电荷在不同位置时对氧化数所产生的影,了定、多酸根等中每个原子氧化数的方法。

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.

本文对巯基乙酸的合成工艺进行了比较研究,认为氢化钠法和酸钠法生产成本低,适宜于选矿用巯基乙酸的生产,而脲法可得到较高浓度的巯基乙酸。
