Sodium Sulfide Sulphide Use in Leather Industry CAS No. 1313-82-2 Inorganic Salt Na2s

Sodium Sulfide (Na2S, commonly known as sulfide alkali) is a highly important inorganic chemical 
raw material with extensive applications across various industrial fields. Below is a detailed summary 
of its main uses:
1. Chemical and Dye Industry
Production of Dyes and Intermediates: Serves as a key raw material and reducing agent in the 
production of sulfur dyes (e.g., sulfur black, sulfur blue), which are commonly used for dyeing 
cotton fibers.
Production of Other Sulfides: Acts as an essential raw material for manufacturing chemicals such 
as sodium hydrosulfide (NaHS), sodium polysulfide (Na2Sx), and sodium thiosulfate (Na2S2O3, 
commonly known as "hypo").
2. Leather Industry
Depilatory Agent: Its aqueous solution is highly alkaline and can break down keratin in hair, loosening 
hair roots. It is a primary chemical used in traditional leather processing for raw hide depilation.
3. Non-Ferrous Metallurgical Industry
Ore Flotation Agent: Utilized in mineral processing as a flotation agent to separate and enrich non-ferrous metal ores (e.g., copper, lead, zinc, molybdenum) by forming insoluble sulfide precipitates 
with various heavy metal ions.
4. Paper Industry
Cooking Agent: Used as a component in the cooking liquor during the Kraft process (sulfate pulping) 
to dissolve lignin in wood, thereby separating cellulose for pulp production.
5. Textile Industry
Dyeing Assistant: Functions as a mordant for certain dyes, helping them adhere more firmly to fibers.
Reducing Agent: Used to reduce certain dyes, allowing them to re-oxidize and develop color after 
dyeing.
6. Water Treatment and Environmental Protection
Heavy Metal Precipitant: Employed in treating industrial wastewater to precipitate heavy metal ions 
(e.g., Hg²+, Cd²+, Pb²+) by forming highly insoluble sulfides, enabling heavy metal recovery and 
compliant wastewater discharge.
7. Electroplating Industry
Electroplating Additive: Used as an additive in certain electroplating processes (e.g., cyanide zinc 
plating, silver-cadmium alloy plating).
Precious Metal Recovery: Applied to precipitate and recover precious metals such as silver from 
waste solutions.
8. Other Applications
Rubber Industry: Used as a vulcanizing agent (referring to auxiliary cross-linking, distinct from elemental sulfur vulcanization) and thermal stabilizer in certain rubber processes.
Pigment Production: Employed in the manufacture of certain inorganic pigments.
Chemical Analysis: Used as a common analytical reagent in laboratories for detecting and identifying 
metal ions.
