摘要:

采用失重法、动电位极化曲线、分子模拟研究了CO₂饱和的3.5%NaCl溶液中,咪唑啉季铵盐 (IAS) 与3种阴离子表面活性剂对Q235钢的缓蚀协同效应。结果表明：IAS与十二烷基磺酸钠 (SDSH) 之间具有较好的缓蚀协同效应,且当二者以1:1的浓度比例复配时,协同效应最明显;IAS与十二烷基苯磺酸钠 (SDBS) 之间同样存在协同效应,但协同效果不显著;而IAS与十二烷基硫酸钠 (SDSL) 之间则存在明显的拮抗效应。3种阴离子表面活性剂对Q235钢均具有一定的缓蚀作用。并利用分子模拟,推测出影响IAS与3种阴离子表面活性剂间的缓蚀协同效应程度的因素。

Abstract：

： The synergistic inhibition effect of imidazoline ammonium salt (IAS) and three anionic surfactants on corrosion of Q235 carbon steel in CO₂ saturated brine solution was studied by using mass loss method, potentiodynamic polarization measurements and molecular dynamics (MD) simulation. It is found that in CO₂ saturated brine solution, there exists a good synergistic inhibition effect between IAS and sodium dodecyl sulfonate (SDSH), and the most significant synergistic inhibition with an inhibition efficiency of 88.5% occurs when the concentration ratio of them is 1:1. The synergism also occurs when using IAS together with sodium dodecyl benzene sulfonate (SDBS). However the antagonism occurs between IAS and sodium dodecyl sulfate (SDSL). Good corrosion inhibition on Q235 carbon steel is also found when only one of the three anionic surfactants is used. The factors affecting the synergism between IAS and the three surfactants were conjectured using molecular simulation.

Key words： CO2 corrosion adsorption synergism antagonism molecular simulation
