Trisulfuryl chloride is an inorganic compound of chlorine, oxygen, and sulfur with the chemical formula S3O8Cl2.[1]
Synthesis
Trisulfuryl chloride is obtained from sulfur trioxide and carbon tetrachloride at 80 °C:[2][3]
- 3SO3 + CCl4 → S3O8Cl2 + OCCl2
Properties
The compound decomposes to disulfuryl chloride and SO3 when heated to 116 °C:[2]
- S3O8Cl2 → S2O5Cl2 + SO3
It fumes in air and hydrolizes slowly in cold water. It is insoluble in concentrated H2SO4.[4]
