摘      要：Mono and bis-4-methylpiperidiniummethyl urea were synthesized,characterized and used as new corrosion inhibitors of mild steel in the acidic *** effect of two compounds on mild steel surface in the 1 mol·L^(–1 )sulphuric acid has been studied by a series of techniques,such as potentiodynamic polarization,weight loss and quantum chemical calculation *** polarization measurements showed that two inhibitors are mixed *** measurements showed that inhibition efficiencies enhanced with increase of inhibitor *** reveals that inhibitive actions of inhibitors were mainly due to adsorption on mild steel *** functional(DFT)calculations have been carried out for the title compounds by performing HF and DFT levels of theory using the standard 6-31G*basis set.
