| 摘要: |
| 目前,油田应用的缓蚀剂绝大部分是以有机胺化合物为主,为了解与控制缓蚀剂中有机胺含量从而充分发挥缓蚀剂的防腐效果,准确地检测缓蚀剂有机胺含量极为重要。采用盐酸-乙醇法与高氯酸非水滴定法,通过不同酸碱指示剂、不同溶剂对3种油田缓蚀剂的胺值进行了对比分析实验。实验结果表明:控制合适的缓蚀剂加量,高氯酸非水滴定法终点变化比较敏锐,结果准确、快速。 |

| Abstract: |
| At present,a majority of corrosion inhibitors applying in oilfield mainly consist of organic amine compounds.In order to understand and control the organic amine content of corrosion inhibitors and give full play to corrosion inhibitors effect,it is very important to determine accurately the organic amine content of corrosion inhibitors.In this paper,the amine value of three organic corrosion inhibitors with hydrochloric and ethanol method,high chlorine acid non-aqueous titration method by different acid-base indicators and solvents were contrastively analyzed.The experimental results show that titration end-point change is acute,accurate,and fast with appropriate addition amount of corrosion inhibitor. |
