Sulfane

Sulfane is elemental sulfur (S) with CAS number 7704-34-9, representing the pure form of the chemical element sulfur. It has a molecular weight of 32.07 g/mol and appears as a yellow crystalline solid at room temperature. Sulfane is classified as a skin irritant (Skin Irrit. 2) under GHS regulations and requires careful handling in industrial applications.

Sulfane is a yellow crystalline solid at room temperature with a characteristic odor. It is insoluble in water but soluble in organic solvents like carbon disulfide. Sulfane has a melting point of 115°C and a boiling point of 445°C. It exists in several allotropic forms, with rhombic sulfur being the most stable at room temperature.

Sulfane is used extensively in the chemical industry for producing sulfuric acid, one of the most important industrial chemicals. It serves as a raw material for manufacturing rubber vulcanization agents, fungicides, and pharmaceutical compounds. Additionally, sulfane is utilized in the production of sulfur dioxide, matches, gunpowder, and various sulfur-containing organic compounds in petrochemical processes.

Sulfane requires careful handling due to its skin irritant properties (GHS07 pictogram, Warning signal word). Wear appropriate personal protective equipment including gloves, safety goggles, and protective clothing to prevent skin contact. Ensure adequate ventilation in work areas and avoid generating dust. Handle in a well-ventilated area away from heat sources and incompatible materials.

Sulfane should be stored in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Keep containers tightly closed and protected from moisture. Store away from metals and organic materials that could react with sulfur. Maintain storage temperatures below 30°C to prevent softening and ensure proper container integrity.

In case of skin contact with sulfane, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, rinse eyes with clean water for 15 minutes and seek medical attention. In case of inhalation of sulfur dust, move to fresh air immediately and seek medical advice if respiratory irritation persists.

Sulfane disposal must comply with local and national waste regulations as it is classified as a chemical waste. Contact licensed waste disposal companies for proper handling and treatment. Small quantities can often be recycled through chemical recovery processes. Never dispose of sulfane in regular household waste or down drains, as it requires specialized treatment facilities.

Sulfane is classified under ADR as Class 4.1 (Flammable solids), Packing Group III, indicating it requires specific transport regulations. Use appropriate UN-approved packaging and ensure proper labeling with hazard diamonds. Transport vehicles must comply with ADR requirements including proper documentation, emergency equipment, and driver training for handling flammable solid materials.

Sulfane is regulated under CLP regulation with classification as Skin Irrit. 2, requiring GHS07 pictogram and Warning signal word. It falls under REACH regulation for chemical registration and safety data requirements. While not classified as SVHC (Substance of Very High Concern), it must comply with standard chemical safety protocols and workplace exposure limits established by national authorities.
