Properties
Chemical
Disulfur dichloride is sensitive to moist air, due to reaction with water:
- 2 S2Cl2 + 2 H2O → SO2 + 4 HCl + 3/8 S8
Physical
Pure disulfur dichloride is a yellow liquid, with a pugnant irritating odor, that smokes in air.
Availability
Disulfur dichloride can be purchased from chemical supplier, however due to it's hazardous nature, it cannot be bought by individuals.
Preparation
Disulfur dichloride can be prepared by bubbling dry chlorine through molten sulfur. Direct chlorination of powdered sulfur also works with lower efficiency. In either case distillation is required for purification.
Projects
- Tetrasulfur tetranitride synthesis
Handling
Safety
Disulfur dichloride will react with water to release HCl and sulfur dioxide.
Storage
Disulfur dichloride should be stored in sealed bottles in a special cabinet. Ground glass is inappropriate as escaping vapour reacts with atmospheric air, depositing solid sulfur in the glass joints, gluing them together.
Disposal
Disulfur dichloride can be neutralized by mixing it with a basic solution. Slaked lime is very good.
