Carbyl sulfate is an organosulfur compound with the formula C2H4(SO3)2. This a white solid is the product of the reaction of sulfur trioxide and ethylene. It is used in preparation of some dyes and other organosulfur compounds.[1]
Reactions
As a cyclic sulfate ester, it is an alkylating agent. Hydrolysis affords ethionic acid:
- C2H4(SO3)2 + H2O → HOSO3C2H4SO3H
Ethionic acid undergoes further hydrolysis to isethionic acid:
- HOSO3C2H4SO3H + H2O → HOC2H4SO3H + H2SO4
Isethionic acid is a precursor to vinylsulfonic acid.
