Product Description

Product: Sodium sulphide
Properties:
Sodium sulphide is also called sodium sulfide, smelly soda,smelly alkali, its molecular formula is Na₂S, with relative molecular mass of 78.04, melting point of 1180ºC. It is easy to dissolve in water, slightly  dissolve in ethanol, and it is insoluble in diethyl ether. Sodium sulphide industrial grade has an appearance of brick red or yellow flakes.
Application:
The main applications are production of sulfur dye and leather depilatory, metallurgy, photograph and rayon denitration and so on.
1.Sodium sulfide is primarily used in the kraft process in the pulp and paper industry.
2.It is used in water treatment as an oxygen scavenger agent and also as a metals precipitant;
3.in chemical photography for toning black and white photographs;
4.in the textile industry as a bleaching agent, for desulfurising and as a dechlorinating agent;
5.in the leather trade for the sulfitisation of tanning extracts.
6.It is used in chemical manufacturing as a sulfonation and sulfomethylation agent.
7.It is used in the production of rubber chemicals, sulfur dyes and other chemical compounds.
8.It is used in other applications including ore flotation, oil recovery, making dyes, and detergent.
9.It is also used during leather processing, as an unhairing agent in the liming operation.
