Apprehend the corrosion of the mild steel (MS) in various environment has been studied. Amide like octylpalmamide (OTP), octylstearamide (OTS), octylcaprilamide (OTC) and dicyclohexylaminebenzotriazole (DCHA.BTZ) compounds exploited as VCI in this paper and tentative its corrosion rate and its inhibition power in corrosive Cl2 gas medium. Weight loss mode used to calculate the former parameter. Surface characterization had been analyzed SEM and FTIR. Electro chemical studies of EIS and Tafel polarization and its parameter were computed by characterization. And find OTS was best VCI in Cl2 medium via the above characterizations. The thermodynamic property adsorption isotherm has been calculated.
