Abstract: Use of iminodiacetic acid derivs. (I) as complexing agent or builder in alkaline cleaning formulations for the drinks and food industries is new. R=H, 1-4C alkyl, CH2CH2X, CH2CHOHX, -C(CH2OH)2X or CHY(-CH2)-nX; X= COOH (opt. as alkali metal or (substd.) ammonium salt) or CONH2 (opt. N substd.); Y = COOH (opt. in salt form as X); Z = H or OH; n = 1 or 2. Also new is an aq. cleaning formulation contg. 0.05-30 wt.% (I); 2-50 wt.% alkali metal hydroxide, carbonate and/or silicate, and 1-30 wt.% surfactant. USE/ADVANTAGE - The compsns. are used to clean bottles and machinery used in dairies, breweries or industries which mfr. and process preserved foods, baked goods, sugar, fat and meat. They give good results for removal of e.g. Ca salt deposits, hop resins, fat and dough residues etc. Unlike known iminodiacetic acid derivs., (I) can be formulated without organic solvents and also have an improved spectrum of activity. (I) are extraordinarily effective chelating agents for alkaline earth metals, e.g. Ca, and have extremely high Ca-binding capacity. They are readily biodegradable and have low toxicity.

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: 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.
