摘要:

合成了4种具有不同亲水基的油酸基咪唑啉衍生物。使用接触角测试、原子力力曲线、动态失重实验和分子动力学模拟研究了它们在20#碳钢表面的亲水和疏水性以及在CO₂/H₂S共存环境中不同流速下对20#碳钢的缓蚀行为。结果表明：静态条件下,侧链含有两个胺基乙撑的咪唑啉的缓蚀效果最好,在缓蚀剂浓度为100 mg/L时,缓蚀率达86.8%;流速为5.5 m/s时,侧链含有3个胺基乙撑的咪唑啉的缓蚀效果最好,在缓蚀剂浓度为100 mg/L时,缓蚀率达73.6%;咪唑啉缓蚀剂的疏水性、粘附力和吸附能均随胺基乙撑数的增多而逐渐增强。

Abstract：

Four oleic acid-based imidazoline derivates with different hydrophilic groups were synthesized in this work. The performance of the synthesized products, such as the hydrophobicity and hydrophily, the adsorption and corrosion inhibition on the 20# carbon steel in flow CO₂/H₂S environment were assessed by means of measurements of contact angle, AFM force curve and mass loss, as well as molecular dynamics simulation. The results showed that under static conditions the imidazoline derivate with two amino ethylene units processes the best inhibition efficiency of 86.8% for the dosage of 100 mg/L, while under high flow rate (5.5 m/s), the inhibition efficiency of imidazoline with three amino ethylene units was the highest, i.e. 73.6% for the dosage of 100 mg/L. The hydrophobicity, adhesion force and adsorption energy of imidazolines were enhanced gradually with the increase of the number of amino ethylene unit.

Key words： CO₂/H₂S imidazoline derivate hydrophilic group flow velocity contact angle AFM MD
