Abstract

The present invention relates to a process for the preparation of substituted alkanesulfonates by the reaction of an aqueous metal substituted 2-hydroxyethanesulfonate with a nucleophile. 2-Alkylaminoalkanesulfonate is formed when the nucleophile is an amine. The invention also relates to the optimization of reaction conditions to produce an optimum yield.
