Hydrochloric Acid → Phenyl ethenesulfonate

Participants

Reaction Steps

The aryl ester of vinylsulfonic acid can be prepared by several available techniques. One method, described in U.S. Pat. No. 3,121,730 to Distler, involves reacting a beta-chloro-ethanesulfonic acid chloride with phenol in an aqueous medium at a pH of between 7.5 and 11.5. The reaction proceeds with a loss of 2 mols of hydrogen chloride to yield phenyl vinylsulfonate. An alternative method, described in U.S. Pat. No. 3,133,948, also to Distler, involves reacting carbyl sulfate with an aromatic hydroxy compound in an aqueous alkaline medium at a pH between 7.5 and 11.5 to yield a phenyl vinylsulfonate.
