咪唑啉型缓蚀剂的合成及其缓蚀机理的研究
SYNTHESIS AND INHIBITION MECHANISM OF AN IMIDAZOLINE CORROSION INHIBITOR
摘 要
以棕榈酸、二乙烯三胺、马来酸酐为原料合成了一种咪唑啉型缓蚀剂YQ-01,与YQ-02复配后得到能有效抑制二氧化碳腐蚀的缓蚀体系YQ-03.应用静态挂片失重法、电化学极化曲线、Ｘ射线光电子能谱分析研究了YQ-03抑制二氧化碳腐蚀的电化学特征,分析了腐蚀前、后及加入缓蚀体系YQ-03后A3钢的表面产物,探讨了YQ-03的缓蚀机理.结果表明,由主剂YQ-01和助剂YQ-02组成的复配缓蚀体系有良好的协同作用,腐蚀产物膜有3层,能有效抑制饱和CO2的高矿化度盐水对A3钢的腐蚀.

Abstract
Imidazoline corrosion inhibitor YQ-01 was synthesized with hexadecanoic acid,diethylene triamine,maleic acid anhydride.And YQ-03 carbon dioxide corrosion resistant system was got by using YQ-01 compounded with YQ-02.Weight-loss method,electrochemical polarization and X-ray photoelectron spectroscopy were used to study the electrochemical properties of YQ-03.The product on the surface of A3 steel after corroded by carbon dioxide with addition of YQ-03 inhibitor was analyzed.The inhibiting mechanism of YQ-03 was studied.The compounded system of major inhibitor YQ-01 and assistant inhibitor YQ-02 had good synergic action and corrosion resistance to carbon dioxide due to the formation of corrosion products with three layers produced on the surface of A3 steel.
