Hydrogen sulfide Uses

Hydrogen sulfide (CAS NO.7783-06-4) is used in the producetion of several organosulfur compounds.
Upon combining with alkali metal bases, hydrogen sulfide converts to alkali hydroSULFIDES such as SODIUM HYDROSULFIDE and sodium sulfide, which are used in the degradation of biopolymers. It was used in analytical chemistry. It is a precursor to metal SULFIDES. It is also used in the separation of DEUTERIUM oxide.

Hydrogen sulfide Production

Hydrogen sulfide (CAS NO.7783-06-4) is obtained by its separation from sour gas, which is natural gas with high content of H₂S. It can be produced by reacting hydrogen gas with molten elemental SULFUR at about 450 °C.

Hydrogen sulfide Safety Profile

HYDROGEN sulfide is a highly toxic and flammable gas. Being heavier than air, it tends to accumulate at the bottom of poorly ventilated spaces. Although very pungent at first, it quickly deadens the sense of smell, so potential victims may be unaware of its presence until it is too late. For safe handling procedures, a HYDROGEN sulfide material safety data sheet (MSDS) should be consulted.
Hazard Codes of Hydrogen sulfide (CAS NO.7783-06-4): Highly F+, Very T+, Dangerous N
Risk Statements: 12-26-50
R12: Extremely flammable.
R26: Very toxic by inhalation.
R50: Very toxic to aquatic organisms.
Safety Statements: 9-16-36-38-45-61
S9: Keep container in a well-ventilated place.
S16: Keep away from sources of ignition.
S36: Wear suitable protective clothing.
S38: In case of insufficient ventilation, wear suitable respiratory equipment.
S45: In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.)
S61: Avoid release to the environment. Refer to special instructions / safety data sheets.
