Abstract: Bisphosphoric acid monoesters of alkylene oxide block polymers of the formula in which x and z are identical and are numbers from 2 to 200, and y is a number from 2 to 200, and salts thereof are prepared by phosphating the parent block polymer. They are suitable as auxiliaries for the preparation of crop-protection agent formulations.

Abstract: Triacylated ethanolamines of the formula… (RCO)(R1CO)N-(CH2)2-OCOR2… in which R, R1 and R2 are identical or different and are alkyl, alkenyl or aryl groups, and the total of all C atoms in the molecule is 8 to 14, are liquid and readily miscible with water. By reason of these properties they are very suitable as peroxide activators in liquid detergents and cleaners.

Abstract: A process is described for the preparation of acyloxybenzenesulphonates which are optionally substituted on the benzene ring. Liquid acyloxybenzene which is optionally substituted on the benzene ring is brought into contact with a gas mixture containing 1 to 7% by volume of SO3 at 20 to 200 DEG C. When 1 mol of the acyloxybenzene which is optionally substituted on the benzene ring has taken up 0.9 to 1.3 mol of SO3, SO3-feeding is stopped, the liquid is held at a temperature of 20 to 70 DEG C for 5 to 180 minutes and then neutralised. In this manner, acyloxybenzenesulphonates which is optionally substituted on the benzene ring can be prepared in good quality and good yield without solvents and without it being necessary to remove troublesome reaction products.

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.
