What Is Sodium Sulfide?

Sodium sulfide or its hydrate, Na2S.9H2O, is a chemical compound having the formula Na2S. The shape of both hydrated and anhydrous salts are solids with no color. They are soluble in water and create extremely alkaline solutions. Hydrogen sulfide, which has a rotten egg stench, is formed when Na2S and its hydrates are exposed to damp air.

Sodium sulfide Uses

In contrast to other known synthetic polymers generated by polymerization of monomers with various vinyl functionalities at the time, sodium sulfide is water soluble. In 2002, NMR research were performed to determine the structure and reaction pathway. Its applications include:

  • Sodium sulfide is widely used in the kraft process in the pulp and paper industry.
  • It is used in water treatment as an oxygen scavenger and metals precipitant.
  • Sodium In chemical photography, sodium sulfide is used to tone black-and-white photographs.
  • It is also commonly used as a bleaching, desulfurizing, and dechlorinating chemical in the textile industry.
  • It is usually found in the leather industry for sulfurization of tanning extracts and unhairing agent in the liming process.
  • It is used as sulfonation and sulfomethylation agent in the chemical industry, especially in the production of rubber chemicals, sulfur dyes, and other chemical compounds.
  • Other uses include ore flotation, oil recovery, dye production, and detergent.


Is Sodium Sulfide Safe?

Sodium Sulfide, like Sodium Hydroxide, is extremely alkaline in certain amounts and can cause skin burns. Acids react quickly with it, forming extremely deadly hydrogen sulfide. Long-term exposure to this material could result in breathing difficulties, coughing, and chemical bronchitis, among other problems.


How Is Sodium Sulfide Made?

Industrially, Sodium Sulfide (Na2S) is produced through carbothermic reduction of Sodium Sulfate, which often includes the use of coal. The salt may be made in the lab by reducing sulfur with sodium in anhydrous ammonia or by reducing sodium in dry tetrahydrofuran (THF) with a catalytic quantity of naphthalene.


Where To Buy Sodium Sulfide in Bulk?

Sodium Sulfide in small quantities may be available in your area. It is preferable, however, to acquire large amounts of Lithium Chloride directly from the producers. They may be able to provide certifications and cost savings that are preferable to buying the chemical in small quantities locally or through a distributor. If you require bulk quantities of this chemical, you can buy Sodium Sulfide on our website or contact us for further details.
