Date Sep. 3, 1992.A mixture suitable for use as a foam-suppressing surfactant additament in cleaning compositions for mechanized cleaning processes comprises at least two mixtures of alkoxylated alcohols I R-O-(C2H4O)x-(C3H6O)y-H (I) where x is an average degree of ethoxylation between 1 and 12, y is an average degree of propoxylation between 1 and 15, one alkoxylated alcohol mixture carries straight-chain or branched C8-C18-alkyl groups as the radical R and one other alkoxylated 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 alkoxylated alcohol mixtures present in a ratio of from 10:90 to 90:10.

    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: O.Z. 0050/40290 Liquid, alkaline detergent formulations which contain as essential constituents a surfactant, water and 0.1-20% by weight of partially esterified copolymers are obtainable by the copolymerization of (a) one or moxe C4-C28-olefins and (b) ethylenically unsaturated dicarboxylic anhydrides of from 4 to 8 carbon atoms in a molar ratio of 1:1 and subsequent partial esterification of the copolymers of the reaction products (A) C1-C30-alcohols,C8-C22-fatty acids,C1-C12-alkylphenols or secondary C2-C30-amines with (B) one or more C2-C4-alkylene oxides or tetrahydrofuran in a molar ratio of (A):(B) of from 1:2 to 1:50 and hydrolysis of the anhyaride groups of the copolymer to carboxyl groups, the partial esterification of the copolymers being carried on until more than 5 to 50% of the carboxyl groups of the copolymers have been esterified.

    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.
