Gas Description

Hydrogen sulfide, molecular formula is H2S, molecular weight is 34.076, it is a flammable acid gas under standard conditions, colorless, smelly egg smell at low concentration, sulfur smell at extremely low concentration, highly toxic (LC50 = 444ppm) <500ppm). Its aqueous solution is hydrosulfuric acid. The molecular weight is 34.08, the vapor pressure is 2026.5kPa / 25.5 ° C, the flash point is <-50 ° C, the melting point is -85.5 ° C, the boiling point is -60.4 ° C, and the relative density is (air = 1) 1.19. Soluble in water, easily soluble in alcohols, petroleum solvents and crude oil. The ignition point is 292 ° C. Hydrogen sulfide is a flammable and hazardous chemical, and when mixed with air, it can form an explosive mixture. When exposed to open flames and high heat energy, it will cause a combustion explosion. Hydrogen sulfide is an important chemical raw material.

The main purpose

  1. Used in the manufacture of synthetic phosphors, electroluminescence, photoconductors, photoelectric exposure meters, etc.
  2. Organic synthetic reducing agent.
  3. For metal refining, pesticide, medicine, catalyst regeneration.
  4. Preparation of various sulfides for the manufacture of inorganic sulfides and chemical analysis such as identification of metal ions.
  5. Hydrogen sulfide can be used in the industrial manufacture of high-purity sulfide (in the reaction of sulfur dioxide); hot springs containing hydrogen sulfide have a certain effect on skin diseases. Hydrogen sulfide is an acid gas, and some metals, such as silver, have chemical reactions. For example, hydrogen sulfide and silver will produce black-brown silver sulfide after contact. The main use of hydrogen sulfide is for chemical identification analysis such as that of metal ions.
