METHOD OF ELECTROCHEMICAL PRODUCTION OF Ni(0) PHOSPHITE AND DIPHOSPHITE COMPLEXES

摘要

FIELD: electrochemical production of Ni(0) phosphite and diphosphite complexes in DC and AC electrolyzer. SUBSTANCE: proposed method is performed in specific-gravity cell containing anode and cathode made from metal at low over-voltage of hydrogen by means of anodic dissolution of metallic nickel in aprotic solvent selected from group containing aceto-nitrile, demethyl formamideand3-pentene nitrile at anodic density of current of 1 to 20 mA/sq cm followed by electroreduction of nickel ions in sad solvent at cathodic density of current of 1-5 mA/sw cm in presence of phosphoric ligands by use of AC or DC and temperature from minus 10 C to 40 C. EFFECT: increased yield of target products. 11 cl, 27 ex
