“…A through literature survey reveals that most of the inhibitors act by adsorption onto the metal surface which takes place through heteroatoms such as N, O, P and S atoms, triple bonds or p electrons of aromatic rings which tend to form stronger coordination bonds. Several nitrogen, oxygen, and sulphur containing heterocyclic compounds such as benzoxazoles [3], benzothiazole derivatives [4], benzimidazoles derivatives [5], triazines [6], pyrazole derivatives [7], pyrimidines derivatives [8], thiosemicarbazones [9], thiophenederivatives [10], thiourea derivatives [11], and quinoxaline derivatives [12] have been reported as good corrosion inhibitors. Literature survey shows that anti corrosive performance of quinazolinones is scanty and benzooxazinones have not been studied, in our knowledge, as mild steel corrosion inhibitors in sulphuric acid medium.…”

“…A few triazine based compounds studied as CIs of metals in acids were reported. It was shown that symmetrical 2,4,6-trisubstituted triazines with various structures weakly inhibited the corrosion of mild steel even in 0.1 M HCl (20°C) [76]. 1,3,5-Triazine 2,4,6triaminoethoxylate (0.05%) is more efficient: according to electrochemical measurements, it provides Z = 91.3% in 1 M HCl (25°C) on carbon steel (composition, mass%: C 0.3; Si 0.02; Mn 0.03; P 0.04; Sn 0.045) [77].…”

“…On the basis of quantum chemical calculations based on up to date software (MOPAC, Gaussian 03), [1][2][3][4][5][6][7][8][9][10][11][12][13] demonstrated that anticorrosive properties of HCs in acid mediums are related with the value of charge on reactive centers of their molecules. The charge value on reactive centers have an effect on the ability of HCs to adsorb on a metal surface and the formation of protective films in the form of complex metal compounds.…”

“…In complex metal compounds, the strength of the "metal-inhibitor" coordination bond corresponds to the electron density on reactive portions of inhibitor molecule [10][11][12]; in neutral and alkaline media, the dependence of anticorrosive activity on dipole moment of molecule (µ) can be detected, which char acterizes its capacity for physical adsorption [13].…”
