Abstract

The Schiff base 3,4,5-trihydroxy-N-(4-hydroxy-3-methoxy benzylidene) benzo hydrazide generated from Gallic acid hydrazide and 4-hydroxy-3-methoxy benzaldehyde by microwave induced irradiation. Reaction showed enhanced yield and less time, easier workup. The characterization of synthesized molecule has been done on the basis of elemental, spectral (FTIR,1HNMR, Mass) analyses and surface morphology by Scanning Electron Microscopic(SEM). The structural composition of synthesized compound have been determined by X- Ray diffraction (XRD). The inhibitive property of Schiff base on the corrosion of mild steel strip in different concentrations (0.5N, 1N, 2N) of H2SO4 were studied using weight loss technique. Absorption of the inhibitor Schiff base 3,4,5-trihydroxy-N-(4-hydroxy-3-methoxy benzylidene) benzo hydrazide on mild steel strip surface was consistent with the Langmuir isotherm.
