Greenway Electrosynthesis: Chelated Zinc EDTA

摘要

A convenient electrochemical synthesis of chelate complex ML4 (M = Zn; L=ethylenediaminetetraacetic acid) were carried out at sacrificial metal electrode (M=Zn) as anode and inert platinum cathode. The metal, as the anode of simple cell, is oxidised in the presence of the parent compound of the ligand (HL) in an organic solvent mixture. Gram quantities of complex can be produced in a few hours; The structural feature and composition of this complex were confirmed by the data of elemental analysis, IR spectroscopy and TGA spectral measurements. The results support the potential usefulness of Zn chelated EDTA complexes as a fertilizer.
