The invention relates to a process for the preparation of
acyloxybenzenesulfonates starting from carbonyl halides and salts of
phenolsulfonic acid which have a low water content. Surprisingly, it was
discovered that acyloxybenzenesulfonates can be prepared in high yields
and good grades, irrespective of the grade or reactivity of the
phenolsulfonic acid derivative, if the reaction of the phenolsulfonic acid
with an alkanecarboxylic acid derivative is carried out in an aliphatic or
aromatic solvent in the presence of 0.5 to 25% by weight of a polyglycol
ether.
