Process for the preparation of acyloxybenzenesulfonates |
| abstract |
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. |
