temperature on the inhibitory behavior of P2 and P3 was investigated. Meanwhile, the inhibition efficiency (IE) was found to depend on the molecule structure and the concentration of piperidine derivatives. The IE for 10−3 M P2 and P2 in 5.5 M H3PO4 is around 90 %. Polarization studies clearly revealed that all the compounds used act as mixed-type inhibitors. Adsorption isotherms were fitted by the
本研究描述了4-苄基哌啶( P1 ),1,6-双(4-苄基哌啶-1-甲酰胺)己烷( P2 )和双(4-苄基哌啶)秋兰姆二硫化物( P3 )的缓蚀作用。使用失重测量和极化技术在5.5 MH 3 PO 4溶液中的低碳钢。研究了抑制剂浓度和温度对 P2 和 P3 抑制行为的影响 。同时,发现抑制效率(IE)取决于分子结构和哌啶衍生物的浓度。10 −3 M P2 和 5.5 MH 3 PO 4中的 P2 约为90%。极化研究清楚地表明,所有使用的化合物均充当混合型抑制剂。吸附等温线由Langmuir等温线拟合。吸附能(\(\ Updelta \ text G}} ^ \ circ _ \ text ads}} \)和\(\ Updelta \ text H}} ^ \ circ _ \ text ads}} \) )和动力学参数进行了评估。在抑制效率与计算的化学指标之间获得了显着
