Abstract
Three new ethylenediamine tetra-acetic acid amide derivatives with aromatic group were synthesized by acylation reaction of ethylenediamine tetraacetic acid dianhydride(1) and amino aromatic acid(2).The structures were confirmed by UV,1H NMR,IR and elemental analysis.The effects of reaction conditions on the yield were investigated.The yield was over 75% at 40 ℃ for 12 h under the reaction conditions of 1 10 mol,n(1) ∶n(2)=1 ∶2 and pH 3~4.
