    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: Hydroxyalkylaminocarboxylic acids have the general formula (I), in which R is hydrogen, a C1-C4 alkyl residue or a group having the formulas -CHR -CH(OH)-R or -CH2)n-COOM, in which n equals 1 to 4; R and R represent independently from each other hydrogen, a phenyl residue or an alkyl or alkenyl residue that may in addition bear phenoxy groups, carboxylic acid C1-C4-alkyl ester groups or ester groups derived from triglycerides based on unsaturated C10-C22 fatty acids and may be interrupted by non-adjacent oxygen atoms, the sum of all C atoms from both residues R and R being at least 4; A is a linear or branched C1-C6 alkylene group that may in addition bear a hydroxyl group and/or a group having the formula COOM, and R and A may form together with the N atom a 5- or 6-membered ring; and M is hydrogen, alkaline metal, ammonium or substituted ammonium. These hydroxyalkylaminocarboxylic acids are useful as complexing agents for alkaline earth and heavy metal ions.

    Abstract: In order to produce N-acylamino carboxylic and N-acylaminosulphonic acids and their alkaline metal salts from industrial alkaline metal salts of aminocarboxylic or aminosulphonic acids with an active content from 50 to 95 % by weight, in relation to the solid content of the industrial alkaline metal salts, and from carboxylic acid alkyl esters, (a) a suspension of solid water-free industrial alkaline metal salts of aminocarboxylic or aminosulphonic acids in carboxylic acid alkyl esters is prepared; (b) the suspension is made to react by admixture of more than 30 and up to 150 % by moles of strong bases into the alkaline metal salts of N-acylaminocarboxylic or N-acylaminosulphonic acids; and (c) if desired free N-acylaminocarboxylic or N-acylaminosulphonic acids are produced therefrom in the usual manner by admixture of acids.

    Abstract: Compound of the formula in which R and R independently of one another are C1-C10-alkyl, C1-C10-alkoxy-C5-C10-cycloalkyl or a C5-C10-aryl radical which can also contain 1 to 3 non-adjacent nitrogen, oxygen or sulphur atoms as hetero atoms in the carbon chain or carbon ring and which can be substituted by 1 to 3 C1-C4-alkyl or -alkoxy groups, R or R can represent a hydrogen atom, or R and R together form a bridge of 2 to 14 carbon atoms, it being possible for some of the carbon atoms also to be part of an aromatic ring system, A represents an n-valent organic radical, and n is an integer equal to or greater than 2.
