    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: Preparation of the trisodium salt of isoserine-N,N-diacetic acid (I) by reaction of acrylonitrile with aqueous hydrogen peroxide to give glycidamide (II) and further reaction of II with the disodium salt of iminodiacetic acid (III) to give I, by carrying out the process continuously and, in it, successively a) reacting together acrylonitrile and aqueous hydrogen peroxide at pH 7-8 and 30-60 DEG C, b) removing unreacted acrylonitrile by distillation, c) passing the reaction mixture over a solid hydrogen peroxide-decomposing catalyst, d) reacting the aqueous solution of II, obtained in this way, with III at pH 7-9 and 40-90 DEG C, e) reacting the resulting solution with a basic sodium compound at pH 9-14 and 60-95 DEG C, f) removing the ammonia which is produced by distillation and g) if desired, working up the aqueous solution of I, obtained in this way, in a manner known per se to give solid I.
