摘要

介绍了一种新型的吲哚嗪类酸化抑制剂。在不含丙炔醇的情况下,它可以在低得多的浓度下表现出有效的缓蚀作用,并具有经济和环境优势。以喹啉、氯化苄和氯乙酸为原料,在一定条件下制备了两种吲哚嗪衍生物。这些吲哚嗪类缓蚀剂都是由一种常用的季铵类缓蚀剂氯化苄喹啉(BQC)合成的。对目标化合物进行纯化,并用元素分析、高分辨率质谱(HRMS)和核磁共振(NMR)等仪器分析方法对其化学结构进行表征。采用失重法、电化学法(动电位极化法和EIS法)和扫描电镜(SEM)考察了吲哚嗪衍生物在15 wt.% HCl、20 wt.% HCl和12%HCl + 3%HF中对N80钢的缓蚀性能。当添加0.1 wt.%的吲哚嗪衍生物时,N80钢在15 wt.% HCl中的缓蚀效率在90℃时分别提高到98.8%和99.1%,而没有丙炔醇的协同作用;而在BQC方面,即使在1.0 wt.%的用量下,N80钢在相同条件下的缓蚀效率也仅达到83.3%。该新型衍生物具有较好的耐蚀性。与BQC相比,衍生物中有更多的活性吸附位点,因此可以更好地粘附在钢表面。因此,牢固吸附的抑制剂将阻止金属表面与H+离子接触,最终提高抑制效果。新型吲哚嗪衍生物作为一种高效缓蚀剂,为酸化过程中的防腐提供了新的策略。

High-efficiency Corrosion Inhibitor for Acidizing: Synthesis, Characterization and Anti-corrosion Performance of Novel Indolizine Derivative
A novel indolizine derivative inhibitor for acidization was introduced. It could exhibit effective corrosion inhibition at a much lower concentration without propargyl alcohol and shows economic and environmental advantages. From quinoline, benzyl chloride, and chloroacetic acid, two indolizine derivatives were prepared under certain conditions. These inhibitive indolizine derivatives were both synthesised from benzyl quinoline chloride (BQC), which one of the conventional quaternary ammonium corrosion inhibitors used for acidising. The target compound was purified and instrumental analysis methods including elemental analysis, high-resolution mass spectrometry (HRMS), and NMR were used to characterise the chemical structure. The inhibition performance of the indolizine derivatives in 15 wt.% HCl, 20 wt.% HCl, and mud acid (12%HCl + 3%HF) for N80 steel was investigated by weight loss measurement, electrochemical method (potentiodynamic polarization and EIS), and SEM surface morphology assessment. When 0.1 wt.% indolizine derivative was added, the inhibition efficiency of N80 steel in 15 wt.% HCl at 90 °C increased to 98.8 % and 99.1 % respectively without the synergistic effect of propargyl alcohol: however, in terms of BQC, even at a dosage of 1.0 wt.%, the inhibition efficiency of N80 steel only reached 83.3 % under the same conditions. The novel derivative could impart an improved corrosion resistance effect. Compared with BQC, there are more active adsorption sites in the derivative and therefore the inhibitor could be better fastened to the steel surface. The firmly adsorbed inhibitors would thereby prevent the metal surface from making contact with H+ ions and finally increase the inhibitory effect. As a high-efficiency corrosion inhibitor, the novel indolizine derivatives may offer a new strategy for corrosion protection in acidising.
