ABSTRACT:
Alkali metal and alkaline earth metal salts of acyloxybenzenesulfonic acids of the formula I ##STR1## where R is a saturated or unsaturated alkyl radical of 1 to 17 carbon atoms or is phenyl which is unsubstituted or monosubstituted or disubstituted by alkyl of 1 to 3 carbon atoms, halogen, methoxy or nitro, are prepared by neutralization, by a method in which a liquid acyloxybenzenesulfonic acid of the formula I and an aqueous solution of an alkali metal or alkaline earth metal hydroxide, carbonate or bicarbonate are combined in water, at from 0.degree. to 60.degree. C. and while mixing thoroughly, so that the pH is kept at from 2.5 to 7.0, and, if desired, the resulting salt is isolated from the aqueous solution in a conventional manner.
