Application:
Color Appearance: yellow flake solid
Sodium hydrosulfide, acid sodium sulfide. From thesulfuric acid or caustic soda solution to absorb hydrogen chloride gas derived.
Appearance and properties: white to colorless, hydrogensulfide odor of the cubic crystal; industrial products are generally orange oryellow.
Colorless needle crystal. Easy deliquescence. Release hydrogensulfide when melting. Soluble in water and alcohol. The aqueous solution isstrongly alkaline. Case of acid, reflect the formation of hydrogen sulfide.Bitter taste.
● Uses:
1. Dye industry for the synthesis of organic intermediates and the preparationof sulfur dyes additives.
2. Tanning industry for hair removal and tanning leather.
3. The fertilizer industry is used to remove the monomersulfur from the activated carbon desulfurizer.
4. Mining industry for a large number of copper oredressing.
5. Man-made fiber production for sulfurous acid dyeing.
6. Sodium hydrosulfide is the production of ammoniumsulfide and pesticide ethanethiol semi-finished raw materials, but also forwastewater treatment.
Storage Precautions: Store in a cool, ventilated warehouse. Away from fire, heat.Should be with the oxidants, acids, edible chemicals stored separately,remember the mixed storage. Explosion-proof lighting, ventilation. Prohibit theuse of mechanical equipment and tools that are prone to sparks. The storagearea shall be provided with an emergency treatment equipment and suitablestorage materials. We should strictly implement the "five pairs"management system of extremely toxic items.
