Abstract: The invention concerns a process for preparing N-acylaminocarboxylic acids and N-acylaminosulphonic acids and their alkali metal salts from the alkali metal salts of aminocarboxylic acids or aminosulphonic acids and carboxylic acid glycerides. The process comprises the following steps: (a) a suspension of the solid anhydrous alkali metal salts of the aminocarboxylic acids or aminosulphonic acids in the carboxylic acid glycerides is prepared; (b) this suspension is left to react by the addition of strong bases to the alkali metal salts of the N-acylaminocarboxylic acids or N-acylaminosulphonic acids; and (c) optionally, the free N-acylaminocarboxylic acids or N-acylaminosulphonic acids are prepared therefrom in the conventional manner by adding acids.

Abstract: Prepn. of 2-(benzylidene or naphthylidene) acylacetic or malonic acid esters or amides of formula Ar-CH=C(COR )(COR ) (I) involves reacting an aromatic aldehyde of formula ArCHO (II) with an active methylene cpd. of formula CH2(COR )(COR ) (III). In the formulae, Ar = phenyl or naphthyl (both opt. substd. by 1-3 or 1-4C alkyl, 1-4C alkoxy and OH); R = 1-8C alkoxy, phenoxy, benzyloxy or -NR R ; R ,R = H or 1-6C alkyl; R = 1-4C alkyl, phenyl, benzyl or as R . The novelty is that the reaction mixt., at the end of the reaction, is washed with aq. alkali metal (hydrogen) sulphite soln. to remove residual, unconverted (II). Pref. the organic solvent in the organic phase obtd. after the (bi)sulphite wash is distilled off to give a technical prod. contg. (I). The use of this technical prod. as brightener is claimed. Preferably, Ar = phenyl (opt. substd. by 1 or 2 of Me, Et, OMe and OEt); R = 1-8C alkoxy; R = 1-4C alkyl or 1-6C alkoxy. Esp. Ar = Ph, R = OMe or OEt, and R = Me, OMe or OEt.

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.
