Abstract

Thiosemicarbazone derivatives and its tin(IV) complexes used in this study were 2-acetylpyridine 4-ethyl-3-thiosemicarbazone (HAcETSc), 2-acetylpyridine 4-methyl-3-thiosemicarbazone (HAcMTSc), 2-acetylpyridine 4-ethyl-3-thiosemicarbazone dichlorophenyltin (Sn(HAcETSc)PhenCl2), and 2-acetylpyridine 4-methyl-3-thiosemicarbazone dichlorophenyltin (Sn(HAcMTSc)PhenCl2). All these title compounds were characterised using an elemental analyser, Fourier-transform infraredattenuated total reflectance spectroscopy (FTIR-ATR), ultraviolet-visible spectroscopy (UV-Vis), and nuclear magnetic resonance (NMR). The efficiency of the synthesised compounds as a corrosion inhibitor of mild steel in 1.0 M HCl was investigated using weight loss technique at different concentrations, 1, 2, and 3 mM, and at a temperature range of 30–60 °C. The thiosemicarbazone ligand and its tin(IV) complexes affirmed the hypothesis where the inhibitor efficiency tends to increase as the inhibitor concentration increases, indicating their potential use as a corrosion inhibitor for mild steel. Moreover, inhibitor efficiency decreases when temperature increases.
硫代氨基脲衍生物及其锡配合物的合成、表征及温度对其缓蚀性能的影响
硫代氨基脲衍生物及其锡(IV)配合物为2-乙酰吡啶- 4-乙基-3-硫代氨基脲(HAcETSc)、2-乙酰吡啶- 4-甲基-3-硫代氨基脲(HAcMTSc)、2-乙酰吡啶- 4-乙基-3-硫代氨基脲二氯苯锡(Sn(HAcETSc)PhenCl2)和2-乙酰吡啶- 4-甲基-3-硫代氨基脲二氯苯锡(Sn(HAcMTSc)PhenCl2)。所有这些标题化合物都使用元素分析仪,傅里叶变换红外衰减全反射光谱(FTIR-ATR),紫外可见光谱(UV-Vis)和核磁共振(NMR)进行了表征。在30-60℃的温度范围内,采用失重法研究了所合成的化合物在1.0 M HCl中作为低碳钢缓蚀剂的效率,其浓度分别为1、2和3 mM。硫代氨基脲配体及其锡(IV)配合物证实了缓蚀剂效率随着缓蚀剂浓度的增加而增加的假设,表明它们作为低碳钢缓蚀剂的潜在用途。随着温度的升高,缓蚀剂的效率降低。
