Abstract: Soluble polyacetals containing acetaldehyde acetal units obtainable by the cationically initiated polymerization of (a) compounds containing at least 3 hydroxy groups and (b) divinyl ethers containing terminal vinyl ether groups or mixtures of such divinyl ethers and monovinyl ethers, possibly in the presence of (c) dihydroxy compounds and/or monohydroxy compounds, a process for producing the polyacetals and their use as an additive to low-phosphate and phosphate-free washing and cleaning agents and as dispersants for finely divided minerals.

Abstract: The use of partially esterified copolymers which can be obtained by copolymerisation of (a) at least one C4- to C28-olefin and (b) ethylenically unsaturated dicarboxylic anhydrides with 4 to 8 C atoms in the molar ratio 1:1 and subsequent partial esterification of the copolymers with reaction products of (A) C1- to C30-alcohols, C8- to C22-fatty acids, C1- to C12-alkylphenols or secondary C2- to C30-amines with (B) at least one C2- to C4-alkylene oxide or tetrahydrofuran in the molar ratio (A):(B) of 1:2 to 50 and hydrolysis of the anhydride groups of the copolymers to carboxyl groups, where the partial esterification of the copolymers is continued until more than 5 to 50% of the carboxyl groups in the copolymers are esterified, as additive to liquid detergent compositions in an amount of 0.1 to 20% by weight and liquid detergent compositions which contain the partially esterified copolymers.

Abstract: Alkali metal and alkaline earth metal salts of acyloxybenzenesulfonic acids of the formula I 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 DEG to 60 DEG 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.

Abstract: Acyloxybenzenesulfonic acids and their alkali metal and alkaline earth metal salts are prepared by sulfonation of phenol in the presence of a small amount of a complexing agent for the sulfonating agent SO3 or chlorosulfonic acid, followed by esterification and, if required, neutralization to give the alkali metal or alkaline earth metal salt.
