Influence of structure of the cationic polytriethanol ammonium bromide derivatives. II. corrosion inhibition

ABSTRACT

A series of alkyl polytriethanolammonium bromide derivatives were synthesized and evaluated as corrosion inhibitors using the weight loss method at 25°C. The applicability of these inhibitors was examined using [2M HCl] at 50, 100 and 200 ppm of inhibitor concentrations. The results were correlated to their surface and thermodynamic parameters of adsorption. The results obtained from emulsification and solubilization measurements showed the ability of using these compounds as corrosion inhibitors in oilfields without any risk for occurrence of emulsification or solubilization processes
