Preparation and Characterization of 1,2,3,4- Butane four Carboxylate Transition Metal Complexes

Abstract

1,2,3,4- butane four carboxylic acidis (Na4C8H6O8) is mainly used to prepare photosensitive materials, medical polymer materials and functional polymer membrane materials.As a permanent finishing agent, 1,2,3,4- butane four carboxylic acid plays an irreplaceable role.In this paper, the preparation of metal complexes by the reaction of 1,2,3,4-butane tetracarboxylic acid tetrasodium salt (Na4C8H6O8) with transition metals is described. The composition and structure of the prepared metal complexes were characterized by infrared spectroscopy, thermogravimetric analysis and elemental analysis. At the same time, through the analysis of thermogravimetric curves, the order of thermal stability of metal complexes is (from large to small): Co2C8H6O8·2H2O > Cd2C8H6O8 ·2H2O > Mn2C8H6O8·2H2O > Ni2C8H6O8·2H2O > Zn2C8H6O8·2H2O > Zn2C8H6O8·2H2O > Cu2C8H6O8 ·2H2O.
