Determination of electronic characteristics of tetrahydro pyrimidine derivatives and investigation of usability as anti-corrosion

Abstract

Corrosion of metallic structures is a serious problem in most industries worldwide. This problem can be controlled by the addition of chemicals capable of adsorption onto the metal surface. The metal can be isolated from the corrosive environment. These chemicals are often selected from groups containing free electron pairs and / or π electrons, which are rich in functional groups. In this study, electronic structures Highest Molecular Orbital (HOMO), Lowest Occupied Molecular Orbital (LUMO), MEP, energy gap (ΔE), ionization potential (I), electron affinity (A), chemical structure of pyrimidine derivative compounds containing unpaired electron pairs, π electrons, functional groups such as N, O and S hardness and softness (S), general electrophilic index (ω), transmitted electron fraction index (ΔN) and recovery (backEback-donation) properties of quantum chemical calculation methods to investigate the properties of the selected compounds in this direction and adsorbed to the surface with the quantum chemical calculation methods. The aim of this study is to determine the efficiency of synthesized compounds as anti-corrosion materials and to provide new gains to the industry in this sense.
