Description
- General description: Sodium sulfide nonahydrate is a chemical compound with the formula Na2S-H2O. It is a white to yellow hygroscopic solid that is highly soluble in water and has a strong, unpleasant odor. Sodium sulfide nonahydrate is typically made by dissolving elemental sulfur in a solution of sodium hydroxide, which leads to the formation of sodium sulfide. The nonahydrate form of the compound is formed by adding excess water to the solution, which leads to the formation of a crystalline solid with nine molecules of water per molecule of sodium sulfide. Sodium sulfide nonahydrate is often used as a reducing agent in chemical reactions as well as a flotation agent in the mining industry. It is also used in the production of dyes, pigments, and other chemicals.
- Application: Sodium sulfide nonahydrate (Na2S.9H2O) can be reacted with α,ω-dibromo and/or α,ω-dichloroalkane for the synthesis of polyalkylene sulfide.[1] It can be used as a reducing agent for the removal of nitrogen oxide from the exhaust gas.[2] Na2S.9H2O can also be used as an inexpensive sulfur source for the synthesis of heterocyclic thiochromes.[3]
