季铵盐双子型表面活性剂的合成及其缓蚀性能
Synthesis and Inhibition Performance of Quaternary Ammonium Salt Gemini Surfactant
摘 要
以邻苯二甲酸为连接基,油酸酰胺为主体,氯化苄为成盐试剂,合成了一种新型的季铵盐双子型表面活性剂(ODOB)。它具有更多的吸附基团,水溶性良好。SEM结果显示,其在钢片表面具有很好的吸附成膜性能,能在碳钢表面形成单分子的吸附层,一个缓蚀剂分子可以取代2.7个水分子。电化学和失重法结果显示,ODOB通过增大反应的活化能来抑制腐蚀速率,其质量浓度为150 mg/L时,在10%的盐酸(25 ℃)中的缓蚀率可以达到99.3%。

Abstract
A new kind of quaternary ammonium salt gemini surfactant(ODOB) was synthesized by oleic amide, phthalic acid and benzyl chloride which were used as main body, bonding group and salt reagent respectively. ODOB has more adsorption groups and good solubility in water. The results of SEM show that ODOB has good adsorption film performance on the steel surface. ODOB can form a single molecule adsorbed layer, and a corrosion inhibitor molecule can replace 2.7 molecules of water. The results of electrochemical test and weight loss method show that ODOB can inhibit the corrosion rate by increasing reaction activation energy, the corrosion inhibition rate was up to 99.3% when its concentration was 150 mg/L.
