Abstract


An Azodye was synthesized using 4-aminophenol acid as the primary aromatic amine and 2, 4-dinitrophenylhydrazine as the coupling agent and labelled AXD1. The antimicrobial activity of the dye was tested on Staph aureus and Staph waneri. The result showed that the AXD1 dye has the potential to inhibit and limit the spread of the said microorganisms. The melting point of the synthesized dye was found to be 192 0C, the wavelength of maximum absorption (max) was 372.00nm. From the FTIR analysis, the following functional group were discovered: C-H, C-H 1, 4- disubstitution, C-H, N-H, C-N, C=C-C, -N-N- , carboxylate. The dye was applied on chrome and vegetable tanned leather which gave well to very good   rub and light fastness on both the chrome   and vegetable tanned leather.  From the results obtained, it can be concluded that the Synthesized Azo dye can be used in the dying of both chrome and vegetable tanned leather.
