PREPARATION OF SOME CHROMIUM AND IRON SCHIFF BASE COMPLEXES AND THEIR STUDIES AS A COLOURING PIGMENTS IN COATING INDUSTRY

Schiff base complexes based on chromium and iron metals have been widely used as metal complex pigments in coating industry. The Schiff base ligand is prepared by the condensation of aromatic amine namely Ortho-anizidin with selected aldehyde namely N,N Dimethyl-Para- amino-benzaldehyde and the microwave technique was used for the preparation of ligand and its metal complexes. The characterization of ligand and its metal complexes were studied using elemental analysis, 1HNMR, spectral UV–Visible reflectance, infrared, magnetic properties, and thermal gravimetric analysis (TGA). The physical properties of solid complexes showed their stability to be formulated as pigments in anticorrosive paint formula, also the mechanical, color properties, corrosion resistance of dry paint films were also examined and showed excellent mechanical, corrosion resistance and color stability.
