Application:
Physical and chemical properties:
Appearance | Yellow or light yellow liquid |
Odour | It has a special odor and can evaporate |
Solubility | Insoluble in water, slightly soluble in ethanol, ether, easily soluble in carbon disulfide. |
Density | 2.0g/cm3 |
Melting point | 119℃ , easy moisture absorption |
Boiling point | 444.6℃,sulfur has a high melting point and a high boiling point and can be easily converted from a solid to a gas. |
Reactivity | Reaction with alkali to produce polysulfide; and bonds with hydrogen and forms the toxic compound hydrogen sulfide, which has a foul smell; sulfur flammable, burning flame is blue, and release sulfur dioxide gas, with pungent odor. |
