methods at various concentrations from 10−3 to 10−6 K. The obtained structures were characterized using NMR spectroscopy. Potentiodynamic polarization measurements showed that 1,5-benzodiazepine derivatives act as a mixed type inhibitor. The various parameters of activation determining the kinetic data such as energy, enthalpy and entropy of the inhibitors were evaluated and discussed. The adsorptive
摘要 苯二氮卓类以其多种应用而闻名。在此,存在和不存在两种合成苯二氮卓类 4-(2-Oxo亚丙基)-1-炔丙基-1,2,4,5-四氢-3H-1,5 的情况下,碳钢在 1 M HCl 溶液中的缓蚀效率使用电位动力学研究了 -benzodiazepin-2-one (PTB) 和 1-decyl-4-(2-oxopropylidene)-1,2,4,5-tetrahydro-3H-1,5-benzodiazepine-2-one (DTB)极化、电化学阻抗谱 (EIS) 方法在 10-3 到 10-6 K 的不同浓度下。使用 NMR 光谱表征获得的结构。动电位极化测量表明 1,5-苯二氮卓衍生物作为混合型抑制剂。决定动能数据的各种活化参数,例如能量、评估和讨论了抑制剂的焓和熵。PTB和DTB的吸附行为遵循Langmuir型等温线。由于更好的抑制性能,吸附的标准自由能为负。可极化连续介质模型中 B3LYP/6-31
