本文使用电位极化、循环极化、交流阻抗及恒电位计时电流等多种电化学技术,研究了本所研制的高效高温浓酸型缓蚀剂——二丙炔氧甲基烷基胺类化合物的缓蚀性能与作用机理以及吸附型有机缓蚀剂的阳极脱附现象。结果表明,炔甲基胺是一类更适用于盐酸的兼有胺和丙炔醇优点而性能更好的高效缓蚀剂。其中,烷基含6和8个碳原子的化合物性能最好。讨论了氯离子协同效应及绥蚀作用机理。 In this paper, the use of potential polarization, cyclic polarization, AC impedance and potentiostat current and other electrochemical techniques, the research developed by our high-temperature concentrated acid corrosion inhibitor - dipropyloxymethylalkylamines Corrosion inhibition property and mechanism of compound and anode desorption phenomenon of adsorption type organic corrosion inhibitor. The results show that alkyne methylamine is a class of more efficient and effective corrosion inhibitor that is more suitable for the advantages of both amine and propargyl alcohol of hydrochloric acid. Among them, the compounds containing 6 and 8 carbon atoms in the alkyl group have the best performance. The synergistic effect of chloride ions and the mechanism of the action of ablation are discussed.
