SYNTHESIS OF CORROSION INHIBITOR FOR IN 0.5 M HYDROCHLORIC ACID MEDIUM AND STUDY OF THERMODYNAMIC MECHANISMS OF ITS INHIBITION
Keywords:
polyethylene polyamine, croton aldehyde, Langmuir, Frumkin, Temkin, adsorption isothermsAbstract
In this article, the PKA-1 corrosion inhibitor was synthesized based on polyethylenepolyamine and croton aldehyde, its structure was analyzed in YAMR and PMR devices, and its formula was proposed. Also, the inhibition mechanism of this corrosion inhibitor was studied through various thermodynamic parameters. Using the Arrhenius equation, the activation energy (Ea), activation enthalpy (∆H) and activation entropy (∆S) of the steel surface in inhibitory and non-inhibitory environments were determined. Along with this, Langmuir, Frumkin and Temkin adsorption isotherms were studied.
