Alkyl hydrogen sulphates. Part I. Hydrolysis in moist dioxan solution
Abstract
The rate of hydrolysis of methyl and ethyl hydrogen sulphates increases by a factor of 107 when the solvent is changed from pure water to moist dioxan. The reaction is acid-catalysed and the reaction species probably is the zwitterion R–O+H–SO2–O–. The effective strength of sulphuric acid in 98% dioxan–2% water was studied with the indicator p-nitroaniline.
