Abstract: New aminodicarboxylic acid-N,N-diacetic acids of formula (I) are prepd. by reacting aminodicarboxylic acids of formula XOOC-(CH2)n-CH-COOX (II), in water and/or an organic solvent, with 2-2.6 mols of HCHO and 2-2.3 mols of liq. HCN at 0-150 deg. C., or with 2-2.3 moles of alkali metal cyanide at 40-100 deg. C., and hydrolysing amide or CN gps. formed, in presence of an acid or a base. Aminodicarboxylic acid-N,N-diacetonitriles of formula XOOC- (CH2)n-CH (N(CH2CN)2 COOX (III), formed as intermediates, are also claimed. In the formulae, X = H, alkali metal, NH4 or ammonium gp. substd. with 1-4C alkyl or hydroxyalkyl; and n = 1-4. USE/ADVANTAGE - (I) are prepd. in high purity and good yield, from easily available cpds., by a simple, efficient process applicable on the large scale and giving almost no loading with inorganic salt. (I) can be used in alkaline media, overcoming corrosion problems. (I) are complex-formers, esp. for alkaline earth and heavy metal ions, and can be used in washing compsns. and solns. to control the content of free heavy metal ions, as bleach stabilisers, e.g. for NaBO3, as builders, and in bleaching textiles, cellulose or paper pulp, to prevent destruction of the bleach system, enzymes, optical bleaches and perfumes by heavy metal ions.

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: Microcapsules containing a bleaching assistant obtained by polymerisation of a monomer mixture comprising (total monomer mixture = 100 wt. %) (a) 5-100 wt. % of at least one ethylenically unsaturated carboxylic acid anhydride, (b) 0-95 wt. % of at least one monoethylenically unsaturated monomer different to monomer group (a), (c) 0-80 wt. % crosslinking monomers having at least two non-conjugated monoethylenically unsaturated groups in the molecule and (d) 0-20 wt. % water soluble monoethylenically unsaturated monomers, in the oil phase of a stable oil-in-water emulsion in the presence of radical forming polymerisation initiators, and optionally continuously or periodically increasing the temperature of the polymerisation reaction mixture during the polymerisation are new. The oil phase of the emulsion contains or consists of the bleaching assistant. Also claimed are washing and cleaning agents containing the encapsulated bleaching agent assistants for the cleaning of textile s.
