1. Overview:

Liquid sulfur is a highly viscous, molten form of sulfur that is typically used in various industrial applications.

2. Properties:

• Chemical Formula: S
• Physical State: Yellowish-orange liquid at temperatures above 115.2°C (239.4°F). Below this temperature, it solidifies into a yellow, crystalline form.
• Density: Approximately 1.8 g/cm³ at 120°C
• Melting Point: 115.2°C (239.4°F)
• Boiling Point: 444.6°C (832.3°F)

3. Reactivity:

Liquid sulfur is relatively stable at high temperatures but can react with oxygen, forming sulfur dioxide (SO₂) or sulfur trioxide (SO₃). It is non-conductive and does not support combustion.

4. Applications:

• Used in the production of sulfuric acid, a key component in fertilizers, chemicals, and industrial processes.
• Employed in vulcanization and the production of synthetic rubbers.
• Used as a degreaser and in the removal of sulfur compounds from crude oil in the oil and gas industry.
• Applied as a fungicide and insecticide in agriculture to protect crops from pests and diseases.

5. Storage and Safety:

Liquid sulfur is typically stored in insulated, pressure-resistant containers to prevent freezing and maintain its molten state. Proper temperature control is essential to avoid accidents.
