摘要:  以油酸、 四乙烯五胺和氯化苄为主要原料合成了咪唑啉季铵盐, 采用有机酸对其进行改性制得水溶
性好的咪唑啉缓蚀剂。考察了反应物物质的量比、 反应时间、 反应温度对缓蚀率的影响。结果表明, 当有机酸与咪
唑啉委铵盐的物质的量比为1 . 1、 反应时间为3h、 反应温度为1 5 0℃时, 得到的改性咪唑啉季铵盐溶解分散性良好。
利用红外光谱对改性后的咪唑啉季铵盐的结构进行了表征, 考察了咪唑啉缓蚀剂在水中的溶解分散性。结果表明,
在质量分数为1 5%的盐酸介质中, 9 0℃时咪唑啉缓蚀剂对碳钢的缓蚀率可以达到8 5%以上。

Abstract: A kind of imidazolinyl quaternary ammonium salt was synthesized with oleic acid, tetraethylenepentamine and benzyl chloride. Then it was transformed into high watersoluble corrosion inhibitor by reaction with organic acid. Some factors, such as the mole ratio of raw materials, reaction time and reaction temperature affecting the anticorrosive capacity of the inhibitor were discussed. As a result, the optimum synthesis conditions is listed below: the molar ratio of organic acid to imidazolinylquaternary ammonium salt 1.1, reaction time 3 h and reaction temperature 150 ℃. The imidazolinebased corrosion inhibitor synthesized under these conditions has better watersolubility, and the corrosion inhibition efficiency to carbon steel is above 85% in the mass of hydrochloric acid aqueous solution is 15% at 90 ℃.

Key words: Imidazoline, Corrosion inhibitor, Modified, Inhibition performance, Methods of coupon weight loss
