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。
Sodium thiosulfate (Na2S2O3), also spelled sodium thiosulphate, is an inorganic compound that is typically available as the pentahydrate, Na2S2O3·5H2O. The solid is an efflorescent (loses water readily) crystalline substance that dissolves well in water. It is also called sodium hyposulfite or “hypo”.
