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.

本文讨论了硫代、连多硫酸根等中所带电荷在不同位置时对氧化数所产生的影响,提出了确定硫代、连多硫酸根等中每个硫原子氧化数的方法。

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,认为硫氢化钠法和硫代硫酸钠法生产成本低,适宜于选矿用巯基乙酸的生产,而硫脲法可得到较高浓度的巯基乙酸。
