The three substituted triazines were synthesized by ultrasound irradiation method and characterized by FTIR, 13C NMR, and 1H NMR. The corrosion inhibition behavior of the synthesized inhibitors on N80 steel in 15% HCl was studied using electrochemical analyses and weight loss methods. All three inhibitors exhibited excellent corrosion inhibition performance, and the best inhibition effect was shown by TZ-3 (93.2% at 800 mg/L). EIS measurements suggest that the corrosion inhibition process is a charge transfer controlled. The PDP results indicated that all the triazines are mixed-type inhibitors. Langmuir adsorption model is the best fit among the other tested isotherms. These molecules can act as promising acidizing corrosion inhibitors for the oil gas industry. FTIR, AFM, and UV-vis studies corroborate the adsorption of inhibitor molecules over the metal surface.
Role of the nucleophilicity of the amino group of benzidines in the synthesis of hemiaminal ethers

This paper presents a study of the reaction between some aromatic amines and formaldehyde in ethanol. Anisidines reacting with formaldehyde produced cyclic or linear aminals (hexahydrotriazines or methanediamines) whilst benzidines produced hemiaminal eth

We develop a visible light-promoted divergent cycloaddition of α-diazo esters with hexahydro-1,3,5-triazines, leading to a series of aziridine and imidazolidine frameworks in average good yield, by simply changing the reaction media used. It is noteworthy that the reaction occurs under sole visible light irradiation without the need for exogenous photoredox catalysts. More significantly, a reasonable reaction mechanism was proposed on the basis of the control experiments and density functional theory calculation results.
