Abstract: Preparation of mixture of alkoxylated alcohols and use thereof as a foam-suppressing surfactant additament in cleaning compositions for mechanized cleaning processes. Preparation of a mixture of alkoxylated alcohols I R-O-(C2H4O)x-(C3H6O)y-H (I) where x is an average degree of ethoxylation of from 1 to 12 and y is an average degree of propoxylation of from 1 to 15, comprises mixing at least two mixtures of alcohols of the general formula R-O-H where one alcohol mixture carries straightchain or branched C8-C18-alkyl groups as the radical R and one other alcohol mixture carries straight-chain or branched C10-C20-alkyl groups as the radical R, subject to the proviso that the two radicals R differ by at least 0.5 in the average number of carbon atoms, and the two alcohol mixtures are present in a weight ratio of from 10:90 to 90:10, with one another and reacting this mixture first with the corresponding amount of ethylene oxide and then with the corresponding amount of propylene oxide. This mixture is useful as a foam-suppressing surfactant additament in cleaning compositions for mechanized cleaning processes.

Abstract: Acyloxybenzenesulfonic acids and their alkali metal and alkaline earth metal salts are prepared by a process comprising sulfonation of a phenyl ester in the presence or absence of a small amount of a complexing agent for the sulfonating agent SO3 or chlorosulfonic acid, subsequent acylation and, if desired, neutralization to give the alkali metal or alkaline earth metal salt, and, if required, subjecting the latter to oxidative bleaching before drying.
