ABSTRACT:
A method of manufacturing methallyl sulfonate, which comprises: forming a sulfur trioxide-dialkyl sulfoxide complex by effecting reaction between sulfur trioxide and dialkyl sulfoxide as mixed at the ratio of more than 0.8 mol of the latter to 1 mol of the former in the presence of an inert solvent; effecting reaction between said complex and isobutylene, in an amount of 0.9-1.2 mols of isobutylene per 1 mol of sulfur trioxide, by applying a temperature in the range of 10.degree.-80.degree.C; and neutralizing the reaction product with a base.
