摘要
环烷酸和羟乙基乙二胺经两步缩合脱水反应生成咪唑啉中间体.再以甲苯为携水剂,用硼酸与该中间体制得环烷酸咪唑啉硼酸酯(NIB),用红外光谱对产品进行了表征.采用静态挂片法对NIB在酸性溶液中的缓蚀性能进行评价.实验结果表明:NIB在酸性溶液中对碳钢挂片、铝挂片、不锈钢具有良好的缓蚀效果.电化学极化曲线得到的结果与失重法定结果一致.NIB缓蚀率随温度先升高后降低;随时间延长缓蚀率先升高后降低.
Firstly the mid-pruduct imidazoline was produced by reaction of naphthenic acid and Hydroxyethyl-ethylenediamine.Then with Toluene being the carrying agent,Naphthenate imidazoline borates（NIB） was synthesized from the intermediate and Boric acid,and the product was characterized by IR.The corrosion inhibition performance of NIB for metals in hydrochloric acid was evaluated using weight method.The result shows that the corrosion inhibition rate on mild steel、 aluminum coupon 、stainless steel is high.The results obtained from electrochemical polarization are consistent with the results obtained form weight loss the Corrosion inhibition rate of NIB decreases with increasing temperature、increases with time then it decreases.
