    Abstract: Preparation of mixtures of low-foam non-ionic surfactants having acetal structure, containing A) 70 to 99% by weight of one or more asymmetrical acetals I where R is a C1- to C30-alkyl radical, a C3- to C30-alkenyl radical or a C7- to C30-aralkyl radical or -alkaryl radical, R is a C1- to C10-alkyl radical, A is a 1,2-alkylene group having 2 to 4 C atoms and x can assume values from 1 to 50, and B) 1 to 30% by weight of one or more symmetrical acetals II where the variables R , A and x have the abovementioned meanings, by reaction of alkoxylates III R -(OA)x-OH (III> with vinyl ethers IV H2C=CH-O-R (IV> in the presence of protic acids or Lewis acids as catalysts, by carrying out the reaction in the presence of one or more acetaldehyde dialkyl acetals V where R is a C1- to C10-alkyl radical and R and R can have the same or different meanings, in an amount from 0.1 to 20 mol of the compounds V per mole of III.

    Abstract: N-alkanoyl-polyhydroxyalkylamines having the formula (I), in which Z stands for the polyhydroxyalkyl residue of a mono- or oligo saccharide; R stands for hydrogen or C1-C8-alkyl and R stands for C1-C21-alkyl are prepared by reaction of polyhydroxyalkylamines having the formula (II): Z-NH-R , with carboxylic acid alkyl esters having the formula (III), in which R stands for a C1-C4-alkyl residue, in the presence of a basic catalyst. For that purpose, (a) the total amount of the ester (III) is taken, is heated up to the reaction temperature and the amine (II) is precisely added thereto as a molten mass while the reaction is in progress, the resulting alcohol represented by the formula R -OH being continuously distilled away; (b) the reaction is carried out at a temperature from 55 to 110 DEG C; and (c) the reaction is carried out in the absence of organic solvents.

    Abstract: Process for the production of polyesters from (a) citric acid or isocitric acid which may be replaced to the extent of up to 29 mol.% by mono or dibasic hydroxy carboxylic acids or by up to 60 mol.% of other di to tetrabasic aliphatic carboxylic acids, and (b) polyhydroxy compounds of the polysaccharide and modified polysaccharide or polyvinyl alcohol group or their mixtures in such a molar ratio (a):(b) that 1.25 to 12 mol of component (a) is used per quantity of component (b) containing 1 mol hydroxy groups, to form condensation products with a K of 8 to 120, and the use of the polyesters as additives in low-phosphate or phosphate-free washing and cleaning agents in quantities of 0.1 to 30 wt % related to the formulation employed.
