China Wholesale Hydrogen Chloride Hcl Factory – Hydrogen Sulfide (H2S) – Taiyu

Technical parameters

Hydrogen sulfide is an inorganic compound with a molecular formula of H2S and a molecular weight of 34.076. Under standard conditions, it is a flammable acid gas. It is colorless and has the smell of rotten eggs at low concentrations. poison. The aqueous solution is hydrogen sulfuric acid, which is weaker than carbonic acid, but stronger than boric acid. Hydrogen sulfide is soluble in water, easily soluble in alcohols, petroleum solvents and crude oil, and its chemical properties are unstable. Hydrogen sulfide is a flammable and hazardous chemical. When mixed with air, it can form an explosive mixture. It can cause combustion and explosion when exposed to open flames and high heat. It is also an acute and highly toxic substance. Low-concentration hydrogen sulfide has effects on the eyes, respiratory system and central nervous system. Inhalation of a small amount of high-concentration hydrogen sulfide can be fatal in a short time. Used in the manufacture of synthetic phosphors, electroluminescence, photoconductors, photoelectric exposure meters, etc. Organic synthesis reducing agent. Used for metal refining, pesticides, medicine, catalyst regeneration. General reagents. Preparation of various sulfides. Used in the manufacture of inorganic sulfides, and also used in chemical analysis such as identification of metal ions. High-purity hydrogen sulfide is used in semiconductor and other fields. It can also be used in national defense chemical industry, pharmaceutical and pesticide intermediates, non-ferrous metal refining and metal surface modification treatment, used in the preparation of standard gas, calibration gas, and chemical analysis such as identification of metal ions. An important raw material for the manufacture of infrared optical materials. Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30°C. Keep the container tightly closed. It should be stored separately from oxidants and alkalis, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment.

Application:

①Production of thioorganic compounds:

Several organosulfur compounds are produced using hydrogen sulfide. These include methanethiol, ethanethiol, and thioglycolic acid.
