摘要
通过研究顺丁烯二酸酐加成反应法测定石油产品二烯值的操作过程,得到采用该方法测定石油产品二烯值时应注意的问题及技术关键点。结果表明:反应溶剂体系沸点的高低、反应装置密封的优劣以及加成反应后体系的静置时间是影响二烯值测定结果的关键因素。指出了采用狄尔斯-阿德耳(Diels-Alder)反应原理测定石油产品二烯值实验过程中应注意的细节操作问题,并建议完善该测试方法的国家或行业标准。
The process of determining diene value of petroleum products by maleic anhydride addi-tion reaction was studied. The results show that the boiling point of the solvent,sealing quality and the length of the stand-by time after the addition reaction are important factors for measuring diene value of petroleum products. Several key technical issues during the process of diene value determination based on the Diels-Alder reaction principle are indicated. The improvement for the national or industrial stand-ard method is suggested.
