Calculation of Corrosion Inhibition Mechanism and Performance Study of Indole and Its Derivatives
In this paper,quantum chemical methods are used to analyze and calculate the molecular structure,charge distribution and orbital energy of three indoles and their lipid derivatives:indole,indole acetic acid methyl ester and indole acetic acid ethyl ester,to analyze and summarize the changing rule of intermolecular forces between Fe atoms and different indoles and their lipid derivatives;and further to evaluate the corrosion inhibition performance by using surface analysis methods.The results show that the corrosion inhibition effect:indole>ethyl indoleacetate>methyl indoleacetate,which provides data support for the future development of indole-based corrosion inhibitors.
