Product Name: Sodium hydrosulfide, Sodium bisulfide
CAS Number: 16721-80-5
Chemical Formula: NaHS
Molecular Weight: 56.06
Appearance: It is a white - to - colorless cubic crystal with a hydrogen sulfide odor. The industrial product is generally a solution, which is orange or yellow.
Melting Point: 55ºC (decomposes).
Solubility: It is highly soluble in water and alcohol, and its aqueous solution is strongly alkaline.
Chemical Properties
It has strong reducing properties and is easily oxidized in the air.
It can react with acids to produce hydrogen sulfide gas. For example, it reacts with hydrochloric acid as follows:
NaHS+HCl=NaCl+H2S↑.
It can also react with some metal salts to form metal sulfide precipitates. For example, when reacting with copper sulfate, the reaction is NaHS+CuSO4=CuS↓+NaHSO4.
Uses
In the Petroleum Industry: It is used for desulfurization of petroleum products. It can react with sulfur - containing compounds in petroleum to remove sulfur and improve the quality of petroleum products.
In the Chemical Industry: It is an important intermediate for the synthesis of various sulfur - containing organic compounds. For example, it is used in the synthesis of thiols, thioethers, and some sulfur - containing heterocyclic compounds.
In the Paper Industry: It is used in the pulping process to remove lignin and improve the quality of pulp.
In the Metallurgical Industry: It is used for ore flotation. It can change the surface properties of ores, making it easier to separate valuable metals from ores.
Safety Information
Sodium hydrosulfide is corrosive and toxic. It can cause severe irritation and burns to the skin, eyes, and respiratory tract. Inhalation of its dust or vapor may cause respiratory tract infections, headaches, dizziness, and other symptoms.
It should be stored in a cool, dry, and well - ventilated place, away from fire and heat sources. It should be kept away from oxidizing agents, acids, and other substances to avoid dangerous reactions. When handling sodium hydrosulfide, appropriate personal protective equipment, such as gloves, goggles, and masks, should be worn. In case of accidental contact or inhalation, immediate first - aid measures should be taken, and medical attention should be sought.
