Physico - chemical properties:
Pure sodium sulfide anhydride is white cubic crystal or particle. With extremely strong moisture absorption, the air is easy to change color, unstable. Relative density 1.8569 ( 14 degrees celsius ), melting point 1180 . Soluble in water ( the solubility is 15.4 / 100ml water at 10 degrees celsius ), the solution is alkaline. Slightly soluble in alcohol, insoluble in ether. Water dissolves strongly alkaline, can burn when touching skin and hair, it is also called sodium sulfide. Sodium sulfide is readily oxidized in the air to generate sodium thiosulfate. Sodium sulfide is easy to Hygroscopy and carbonization in the air, and it releases hydrogen sulfide gas. Industrial sodium sulfide due to the magazine, its color is pink, brown, soil yellow. Its specific gravity, melting point, boiling point, also due to the influence of impurities.
use
The dye industry is used for the production of sulfur dyes; The combustion improver for dissolving sulfur dyes in printing and dyeing industry; In the leather industry, it is used to hair removal unhairing, and it is also used to prepare sodium sulfide to accelerate dry skin soaking. A cooking agent used as a paper in the paper industry; The reduction of denitration and nitrification in the textile industry, as well as the dyeing of cotton fabrics with a mordant; In the pharmaceutical industry, for the production of Antipyretic and other antipyretic drugs; In addition, it can be used to produce sodium flow, sodium polysulfide, sodium Rachel, etc.
