COMPLEXONATES OF ETHYLENEDIAMINE-β-PROPIONIC ACIDS WITH DIVALENT METALS: COPPER, ZINC, NICKEL AND COBALT, AND METHODS FOR PRODUCTION THEREOF

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to chemistry of ethylenediamine propionic acids and directly relates to complexonates of ethylenediamine-β-propionic acids with divalent metals: copper, zinc, nickel and cobalt. Complexonate has general formula (R₁R₂NCH₂CH₂NR₃R₄)_nM, where M=Cu(II), Zn(II), Ni(II), Co(II); R₁, R₂=H; R₃=H, CH₂CH₂COO; R₄=CH₂CH₂COO; n=1.2. Also disclosed are methods of producing complexonates.;EFFECT: said complexonates can be used as chelates in medicine, agriculture and other fields.;4 cl, 8 ex
