    Abstract: Pure alkali salts of amino-polycarboxylic acids of general formula (where R1 is H or -CH2-COOH or -CH2-CH2-OH; A is -ch2cooh or a gp. of formula in which R2 is defined as for R1 and n is 0-5). prepared by the reaction of alkali cyanide or formaldehyde, and opt. on a cpd. of formula R3-NH-CH2-CH2-(NH-CH2-CH2-)nNHR4 (in which R3 and R4 are H or -CH2CH2OH) with separation of the solid alkali salt by partial evaporation of the soln. until about 50% of the theoretical amt. of salt is pptd. and recycling the mother liquor after filtering. The process is used partic. for preparing the salts of nitrilotriacetate, ethylenediamine tetra-acetic and hydroxyethylene diamine triacetic acids.

    Abstract: Phenolic binders for printing inks These are prepared by condensation in aqueous solution of a phenol with-per mol. of phenol-0.05-2 Mol formaldehyde and at least 0.01 mol of a polyvalent alcohol at pH >7 and elevated temperature. This is followed by reaction with 0.01 - 3 mol of an aromatic oxycarbonic or oxysulphonic acid or an aryl fatty acid at pH 7. and if necessary drying.
