Abstract
An alkali-metal salt of an alkoxysulfonated benzoic acid glycol ester is prepared by reacting a meta- or para-hydroxy substituted benzoic acid with an alkali-metal alkoxide and a solvent reactant consisting essentially of an alkylene glycol, and then reacting the formed glycol ester with an alkane sultone.
