一种抑制碳五双烯烃自聚或共聚的方法
摘要：
本发明涉及一种在石油碳五馏分分离过程中抑制碳五双烯烃自聚或共聚的方法，该方法在碳五馏分物料中加入阻聚剂，使阻聚剂在碳五馏分物料中维持一定的量，阻聚剂由组分A为N，N-二乙基羟胺，组分B为N，N-二仲丁基对苯二胺，组分C为丁二酰亚胺组成，组分A、组分B、组分C的重量比为(0.1～3)∶1～3∶0.1～3，碳五馏分物料中阻聚剂维持的量以组分A、组分B和组分C的总量计为20～600ppm；本方法所用的阻聚剂阻聚效果好，具有较好的通用性，各组份和溶剂与碳五馏分中的异戊二烯、环戊二烯(或双环戊二烯)以及间戊二烯等双烯烃存在较大的沸点差，可以随分离过程被分离，无需另行增加分离过程。
摘要（英）：

The invention relates to a C5 diolefin auto-agglutination or copolymerization inhibition method in C5 fraction separation process of petroleum, a polymerization inhibitor is added into a C5 fraction material, the polymerization inhibitor in the C5 fraction material is maintained at a certain amount, the polymerization inhibitor comprises component A N, N-diethylhydroxylamine, component B N,N'-di-sec-butyl-1,4-phenylenediamine and component C succinimide, the weight ratio of component A to component B to component C is (0.1-3):1-3 :0.1-3, and taking the total amount of the component A, component B and component C as a reference, the polymerization inhibitor in the C5 fraction material is maintained at the amount of 20-600ppm; the polymerization inhibitor used in the method is good in polymerization inhibition effect and good in versatility, a big difference in the boiling point between each component and solvent and isoprene, cyclopentadiene (or dicyclopentadiene), piperylene and other diolefins in C5 fraction is existed, so that the components and solvents can be separated in the separation process without further increase of a separation process.
