CAS No. 7783-6-4 Hydrogen Sulfide Factory. Characteristics of Hydrogen Sulfide
Hydrogen sulfide (H₂S) is a toxic, colorless gas known for its strong, foul, rotten egg smell at low concentrations. At higher concentrations, however, the smell may not be noticeable because it can quickly deaden the sense of smell. H₂S is heavier than air and is flammable. It is commonly found in many industrial operations and natural sources such as volcanic gases, hot springs, and crude petroleum.
Characteristics of Hydrogen Sulfide:
Chemical Properties:
Molecular Formula: H₂S
Molecular Weight: 34.08 g/mol
CAS Number: 7783-0-4 (The correct CAS number is actually 7783-0-6)
Boiling Point: -60.25 °C

Physical Properties:
Hydrogen sulfide is a gas at room temperature and pressure.
It is soluble in water and is a weak acid.
It is heavier than air, which means it tends to accumulate in low-lying areas.
Toxicity:
Hydrogen sulfide is extremely toxic, causing respiratory paralysis and can be fatal at high concentrations.
It can cause eye irritation, headaches, dizziness, and at high levels, immediate collapse and death.
Uses:
In the processing of ores containing sulfur.
In the pulp and paper industry.
In the production of elemental sulfur and sulfuric acid.
As a reducing agent in chemical synthesis.
Handling and Storage:
Hydrogen sulfide must be handled with great care due to its toxicity.
It should be stored in a well-ventilated area and away from any sources of ignition.
Protective equipment should be worn when handling H₂S.
When seeking a supplier, it's important to ensure that all local and international regulations are followed, and that your facility has the proper safety measures in place to handle the gas safely. Always consult with health and safety experts when planning to work with hydrogen sulfide or any other hazardous substances.
