Abstract: 1. A process for the preparation of an acyloxybenzenesulfonic acid of the formula see diagramm : EP0207445,P6,F1 in which R denotes a (C1 -C17)-alkyle or (C2 -C17 )-alkenyl radical, or alkali metal, alkaline earth metal or ammonium salts thereof, employing the stages (a) sulfonation of phenol, (c) esterification of the sulfonated phenol and, if appropriate, (d) neutralization of the ester, which comprises subjecting the sulfonation intermediate product of stage (a) to heat treatment at a temperature of 50 to 110 degrees C in a stage (b) before the esterification.

Abstract: A process for bleaching raw textiles comprises treating the material with an aq. bleach bath contg. H2O2 and a N-acyl-lactam of formula (I) as bleach activator. In (I) n = 3-5; and R = 1-5C alkyl. Pref. the mole ratio of (H2O2):(I) in the bath is (1-5):1, pref. (1.1-1.5):1, w.r.t. active CO gps. in (I), and the bath liq. has a pH of 5-13, pref. 7-9. The process may be operated as a continuous process using an impregnation method, pref. comprising wetting and impregnating, laying down cold for 0.5-24 hrs. or heating to 95-120 degrees C. with steam, and then washing. Or a discontinuous extn. method may be used, in which the material is wetted and impregnated with the bleach in the cold or at 40-130 degrees C., the wt. of the bleach bath being 3-50 times that of the unbleached material.
