New unsymmetrical Schiff base namely (2-hydroxy-3-((E)-(2-((E)-(4-oxo-4H-chromen-3-yl) methyleneamino) phenylimino)methyl) Benzoic acid) was prepared and characterized by IR, HNMR,C13NMR and EI-mass .The inhibition effect on thecorrosion of carbon steel in industrial water have been investigated at different temperature using weight loss and Tafelpolarization measurements. The effect of time and temperature on activity were studies and compared with standardcommercial inhibitor also the antibacterial activity of synthesized Schiff base against four types of bacteria which iscommonly known in oilfield were tested.
