咪唑啉类缓蚀剂在模拟再生塔顶介质中的应用
APPLICATION OF IMIDAZOLINE INHIBITORS TO THE SIMULATED CORROSION ENVIRONMENT OF AMINE LIQUIED REGENERATOR
摘 要
通过红外光谱、腐蚀失重及电化学测试等方法,探讨了以油酸和二乙烯三胺合成咪唑啉类缓蚀剂时二者配比对缓蚀剂缓蚀性能和稳定性的影响,并找到了最佳配比；在模拟胺液再生塔塔顶介质条件下对缓蚀剂缓蚀性能进行了评价,经复配后的咪唑啉缓蚀剂在该环境中具有良好的缓蚀性能.

Abstract
The effect of the mixture ratio of the raw materials on the performance of imidazoline inhibitors synthesized by oleic acid and diethylene-triamine was studied by means of infrared spectrum,weight loss test and electrochemical test.The best ratio was found as 1∶1.1.The inhibitor mixed by using imidazoline and another assistant with a certain ratio showed a good function in the simulated corrosion environment of the overhead of amine liquid regenerator.
