CAS Number 1313-82-2 Na2S Flakes 78.04 Sodium Sulphide Red Flakes

Product Specification

Na2S Industrial grade sodium sulfide, with colors of pink brown red and earthy yellow

Product Introduction:

Sodium sulfide, also known as stinky alkali, stinky soda, yellow alkali, or sulfide alkali. Sodium sulfide is an inorganic compound, and pure sodium sulfide is a colorless crystalline powder. Highly hygroscopic and easily soluble in water. The aqueous solution exhibits a strong alkaline reaction. Touching the skin and hair can cause burns. Sodium sulfide is commonly known as sulfide alkali. Sodium sulfide aqueous solution will slowly oxidize into sodium thiosulfate, sodium sulfite, sodium sulfate, and sodium polysulfide in air. Due to the fast generation rate of sodium thiosulfate, the main product of oxidation is sodium thiosulfate. Sodium sulfide undergoes deliquescence and carbonation in the air, constantly releasing hydrogen sulfide gas. Industrial sodium sulfide has colors of pink, brownish red, and earthy yellow due to impurities. The specific gravity, melting point, and boiling point also vary due to the influence of impurities.

Basic Product Information:

Product Usage:

1. In the dye industry, it is used to produce sulfurized dyes and is the raw material for sulfurized blue and sulfurized blue. Used in the printing and dyeing industry as a dye aid for dissolving sulfurized dyes. In the leather industry, it is used for hydrolysis to remove hair from raw hides, and also for preparing sodium polysulfide to accelerate the soaking and softening of dry hides. Used as a cooking agent for paper in the papermaking industry. Used in the textile industry for denitrification of artificial fibers and reduction of nitrates, as well as as as a mordant for dyeing cotton fabrics. The pharmaceutical industry is used to produce antipyretic drugs such as phenacetin. In addition, it is also used to produce sodium thiosulfate, sodium hydrosulfide, sodium polysulfide, etc.

2. Adding an appropriate amount of sodium sulfide to the alkaline etching solution of aluminum and alloys can significantly improve the surface quality of etching, and can also be used for the removal of alkaline soluble heavy metal impurities such as zinc in the alkaline etching solution.

3. Sodium sulfide can also be used for the treatment of conductive layers in direct electroplating, by reacting sodium sulfide with palladium to form colloidal palladium sulfide, achieving the goal of forming a good conductive layer on non-metallic surfaces.

4. Used as a corrosion inhibitor. It is also a raw material for sodium thiosulfate, sodium polysulfide, sulfur dyes, etc.

5. Used for manufacturing sulfurized dyes, leather depilators, metal smelting, photography, artificial silk denitrification, etc.
