Sulfur tetrachloride is a chemical compound from the group of inorganic sulfur compounds and chlorides .

Extraction and presentation

Sulfur tetrachloride is made by the direct chlorination of sulfur with chlorine .

properties

Sulfur tetrachloride is only stable in the solid state and down to below −20 ° C, above it it decomposes, producing chlorine and sulfur dichloride . In the solid state, it is a white, finely powdered substance. In the interval down to −20 ° C it melts with simultaneous decomposition. With water it hydrolyzes to form hydrogen chloride and sulfur dioxide .
