    Abstract: Nickelized shaped articles are produced by electrodeposition of nickel from aqueous acidic baths containing as essential constituents one or more nickel salty, one or more inorganic acids and at least two brighteners by using as brightener a mixture of A) from 2 to 98% by weight of one or more cyclic N-allylammonium or N-vinylammonium compoundo I (I) where the nitrogen atom is part of a pyridine, quinoline or isoquinoline ring system which may additionally carry one or two C1- to C4-alkyl substituents or halogen atoms, R1, R3 and R4 are each hydrogen or C1- to C4-alkyl, R2 is hydrogen or methyl, m is from 0 to 4, n is from 1 to 4, and X? is an n-valent inorganic or organic anion which promotes solubility in water, and B) from 98 to 2% by weight of one or more acetyleni cally unsaturated compounds II R1 - C ? C - R5 (II) where R4 and R5 are identical or different and each is C1- to C4-alkyl substituted by hydroxyl, sulfo, amino, C1- to C4-alkylamino or di(C1- to C4-alkyl)-amino, although hydroxyl groups may have been reacted with from 1 to 10 mol of a C1- to C4-alkylene oxide or a mixture of such alkylene oxides and one of the radicals R4 and R5 may also be hydrogen or C1to C4-alkyl.

    Abstract: Preparation of the trisodium salt of isoserine-N,N-diacetic acid (I) by reaction of acrylonitrile with aqueous hydrogen peroxide to give glycidamide (II) and further reaction of II with the disodium salt of iminodiacetic acid (III) to give I, by carrying out the process continuously and, in it, successively a) reacting together acrylonitrile and aqueous hydrogen peroxide at pH 7-8 and 30-60 DEG C, b) removing unreacted acrylonitrile by distillation, c) passing the reaction mixture over a solid hydrogen peroxide-decomposing catalyst, d) reacting the aqueous solution of II, obtained in this way, with III at pH 7-9 and 40-90 DEG C, e) reacting the resulting solution with a basic sodium compound at pH 9-14 and 60-95 DEG C, f) removing the ammonia which is produced by distillation and g) if desired, working up the aqueous solution of I, obtained in this way, in a manner known per se to give solid I.
