The Corrosion Inhibition performance of Ethyl substituted Piperidones namely 3Ethyl 2, 6-Diphenyl Piperidin-4-one (DPN) and 3, 5-Diethyl 2, 6-Diphenyl Piperidin-4-one (EDPN) on mild steel in 1M H2SO4 was studied by Weight loss measurement. The adsorption was spontaneous and followed Langmuir adsorption isotherm. Thermodynamic parameters were calculated for the adsorption process. The inhibition action of Piperidones is taking place by adsorbing on the metal surface in perpendicular direction using Nitrogen as anchoring site. The Nitrogen uses its lone pair of electrons with the vacant d orbital on the Fe-atoms. The inhibition efficiency of 3, 5-Diethyl 2, 6-Diphenyl Piperidin-4-one is comparatively more than 3-Ethyl 2, 6-Diphenyl Piperidin-4-one.
