Abstract: Use of glycine-N,N-diacetic acid derivs. of formula (I) is claimed as complex formers for alkaline earth or heavy metals. R = 1-20C alkyl, 2-20C alkenyl or -A.CH(COOM).N(CH2COOM)2; A = 1-12C alkylene or a chemical bond; M = H, alkali metal or opt. substd. ammonium. The use of ~a-alanine-N,N-diacetic acids as builders in textile-washing powders or as Ca sequestrants in oral hygiene compsns. is specifically excluded. Also claimed are 2-alkylglycine-N,N-diacetonitriles or 2-alkylglycinenitrile -N,N-diacetonitriles (where alkyl = 1-20C alkyl or 2-20 C alkenyl); and cpds. of formula (II). X = carboxylic acid or nitrile function. Cpds. of formula (I) are new except when R = 1-3C alkyl and A = chemical bond.

Abstract: Use is claimed of hexane-1,3,6-tricarboxylic acid (I) (or its ammonium or alkali metal salts) as a complex-former, (co) builder or incrustation inhibitor, the (I) or salt preferably being obtained by hydrolysis of the tricyano by-products obtained in either (a) the Sohio process for acrylonitrile production or (b) the electrohydrodimerisation of acrylonitrile.

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.
