摘要
以油酸、二乙烯三胺为原料合成了咪唑啉中间体,对其改性得到了水溶性咪唑啉基季铵盐,利用红外光谱对其结构进行了表征,通过静态挂片、极化曲线法等测试方法评价了在1 mol/L的HCl中对Q235碳钢的缓蚀性能,并探讨了咪唑啉季铵盐的清蜡性能.实验结果表明:该缓蚀剂溶解分散性及表面活性好,能有效阻止盐水介质中的腐蚀,对Q235碳钢在1 mol/L的HCl体系中的腐蚀具有明显的抑制作用;通过将咪唑啉季铵盐与异丙醇复配,咪唑啉季铵盐不但具有缓蚀、防腐性能,还具有清蜡性能.
Imidazoline intermediate was synthesized from oleic acid and diethylenetriamine.Then modificated to be water-soluble imidazoline-quaternary-ammonium-salt.The structure was analyzed with infrared spectroscopy（IR） spectrum.Using weight loss method,electrochemical polarization curve and other test methods to evaluate the inhibition efficiency of the product on Q235 steel in the medium of 1 mol/L HCl.And discussed the effection of the imidazoline quaternary ammonium salt to clear away wax.Results showed that the inhibitor had good soluble dispersion,good surface activity,strong corrosion resistance to salt solution.and had an apparent inhibition to the corrosion of the Q235 carbon steel in 1 mol/L HCl system.Through the combination use of imidazoline quaternary ammonium salt and isopropanol,not only does the product have inhibition to corrosion,but also has a good perforce to clear away wax.
