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.

超声辅助合成取代三嗪及其在N80钢/酸界面上的缓蚀性能

通过超声辐射法合成了三种取代的三嗪，并通过FTIR，¹³ C NMR和¹表征1 H NMR。利用电化学分析和失重法研究了合成缓蚀剂对N80钢在15％HCl中的缓蚀性能。三种抑制剂均表现出优异的缓蚀性能，TZ-3表现出最佳的缓蚀效果（800 mg / L时为93.2％）。EIS测量表明，腐蚀抑制过程是受电荷转移控制的。PDP结果表明，所有三嗪都是混合型抑制剂。Langmuir吸附模型是其他测试的等温线中的最佳拟合。这些分子可以作为石油工业中有希望的酸化腐蚀抑制剂。FTIR，AFM和UV-vis研究证实了抑制剂分子在金属表面上的吸附。
