Chromeno pyrimidine (CPs) derivatives were synthesized using green approach that involves reaction of multicomponent in one pot using water as solvent. The CPs molecules were tested as potential corrosion inhibitor for N80 steel in 15% hydrochloric acid solution using standard techniques such as weight loss (WT), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP). CPs are effective corrosion inhibitors giving inhibition efficiency of 96.4% at only 200 mg/L concentration (CP-1). Adsorption of CPs with metal surface involve both physical and chemical interactions. EIS results depicted an increase in charge transfer resistance with increase in concentration of CPs. PDP study suggests mixed mode of CPs inhibition action. The adsorbed inhibitor film was confirmed by AFM and XPS spectra.

Chromeno嘧啶（CPs）衍生物是使用绿色方法合成的，该方法涉及使用水作为溶剂在一个罐中进行多组分反应。使用标准技术，例如重量损失（WT），电化学阻抗谱（EIS）和电势极化（PDP），将CPs分子作为15％盐酸溶液中N80钢的潜在腐蚀抑制剂进行了测试。CPs是有效的缓蚀剂，仅在200 mg / L的浓度下（CP-1）抑制率为96.4％。CPs与金属表面的吸附涉及物理和化学相互作用。EIS结果描述了电荷转移电阻随CP浓度的增加而增加。PDP研究表明CP抑制作用的混合模式。通过AFM和XPS光谱确认了吸附的抑制剂膜。
