Hydrogen Sulfide H2S Gas

Description

Hydrogen sulfide (H2S) is a colorless and highly toxic acidic gas. It is an inorganic compound. It has no obvious smell at high concentrations, has a strong smell of rotten eggs at low concentrations, and has a sulfur smell at very low concentrations. In industrial applications, hydrogen sulfide is used in the flotation process of sulfide ores and is also an important raw material for the production of sulfur and sulfuric acid. Furthermore, in laboratories it is used as an analytical reagent, for example in the qualitative analysis of heavy metal ions.

Typical Application

• 
  Pesticide and pharmaceutical production
  In the manufacturing process of pesticides and pharmaceuticals, hydrogen sulfide can be used as an intermediate or reactant.
  
  
• 
  Analytical chemistry
  Hydrogen sulfide can react with metal cations to form water-insoluble sulfide precipitates, which are used for the separation and determination of metal ions.
• 
  Disinfectant
  Hydrogen sulfide has a strong bactericidal effect and can be used for disinfection in industrial production processes.
• 
  Desulfurizer
  Hydrogen sulfide can react with sulfuric acid to form hydrogen sulfide acid, which is used to remove hydrogen sulfide from petroleum and natural gas to reduce environmental pollution.
