摘要
综述了近年来的C_(9)馏分分离环戊二烯和甲基环戊二烯的工艺,包括解聚反应-精馏、反应精馏、萃取精馏的研究应用进展。重点阐述了解聚反应-常压精馏、共沸精馏-解聚反应-常压精馏、减压精馏-解聚反应-常压精馏等几种工业上常用的解聚反应-精馏工艺的操作条件和技术优势,并指出阻聚剂的开发、工艺流程的优化、反应精馏技术的应用等方面是未来C_(9)馏分分离工艺的发展方向。
The recent research related to the separation process of cyclopentadiene and methyl cyclopentadiene from C_(9) fraction,including the process from the depolymerization reaction to the atmospheric distillation,reactive distillation and extractive distillation,were reviewed.Especially the process from the depolymerization reaction to the distillation,the continuous process from the azeotropic distillation to the depolymerization reaction and to the normal distillation,and the continuous process from the vacuum distillation to depolymerization and to the atomospheric distillation were emphasized.Moreover,the operating conditions and technical advantages of these processes were also discussed.Besides,the development of polymerization inhibitor,the optimization of chemical process,and the industrial application of reactive distillation technology will become the directions of the separation of C_(9) fraction in the future.
