    Abstract: Amido-nitriles of formula (I) are new: R1-CO-NR2-A-CN (I) R1 = 1-30C alkyl, 2-30C alkenyl, 5-18C cycloalkyl, 6-18C aryl or 3-18C heteroaryl, optionally containing 1-5 substituents chosen from OH, 1-4C alkyl, 1-4C alkoxy, amino groups, (di-)1-4C alkylamino, Cl, Br, NO2, CN, COOH,. sulpho groups, carboxy-1-4C alkyl, carboxamide, phenyl, tolyl or benzyl, or the chain may contain 1-8 non-adjacent O atoms, amino groups, 1-4C alkylamino groups or carbonyl groups, and it may also be substituted by a group of formula -CO-NR2-A-CN (i) ; R2 = H or 1-6C alkyl ; and A = 3-20C 1,3-, 1,4- or 1,5-alkylene. Also claimed is the preparation of amidocarboxylic acids or their derivatives of formula R1-CO-NR2-A-CO-R4 (IV) by partially or completely hydrolysing (I) and reacting them with alcohols, phenols or oxygen-transferring compounds during or after hydrolysis : R1 = as for (I) except that it can also contain a group of formula -CO-NR2-A-CO-R4 (ii) as a substituent ; and R4 = OH, NH2, OOH, (cyclo)alkoxy, alkenyloxy, arylalkoxy or (hetero)aryloxy, in which the organic groups may contain one or more substituents.

    Abstract: N-benzyliminium salts have formula (I), in which R and R represent independently from each other hydrogen or optionally substituted alkyl, alkenyl, cycloalkyl, aralkyl, heteroaralkyl, aryl or heteroaryl, provided that at least one of the rests R or R has at least 5 C atoms, if it is an aliphatic rest, or at least 7 C atoms, if it is a cyclic rest; R stands for an organic or inorganic substituent; m equals 1, 2 or 3; and X stands for an oxidation-resistant anion, while n indicates the valence of anion X. These N-benzyliminium salts are used as bleach catalysts, in particular in textile washing and bleaching systems.

    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.
