摘要石油化工是推动世界经济发展的支柱产业之一，而乙烯是石油化工的龙头产品。分离乙烯/乙烷是石油化工中重要的分离过程。目前，在工业中一直使用低温精馏方法分离乙烯/乙烷。尽管精馏是一种非常成熟的工艺，但能耗巨大，研究人员一直致力于寻求一种高效、节能、低成本的方法以取代低温精馏。π络合吸附分离作为一种介于物理吸附和化学吸附之间的新型吸附分离技术，引起了科学研究者的广泛关注，其关键是开发具有高选择性的π络合吸附剂。86216

本论文利用[CuI(CH3CN)4][BF4]与2, 2'-联吡啶(2, 2'-bpy)、1, 10-菲啰啉(1, 10-phen)反应，得到了两例Cu配合物[CuII2(O2CCH3)(OH)(OH2)(phen)2][BF4]2 ∙H2O（1）和[CuI2(bipy)2(OH2)2][BF4]2（2）。利用单晶X-射线衍射仪测定其晶体结构和利用IGA-100智能重量吸附仪表征其吸附分离乙烯/乙烷性能。结果表明，在配合物1中的金属离子是二价铜，从而不具备分离乙烯/乙烷性能；而配合物2中的吸附位点较少，从而导致吸附分离性能较差。

Abstract Today, ethylene is the leading products in petrochemical industry, promote the development of world economy。 Ethylene-ethane separation represent a class of the most important as well as most expensive separations in the chemical and petrochemical industry。 Cryogenic distillation has been used for many years for these separations from olefin plants。 They remain to be the most energy-intensive distillations because of the close relative volatilities of the components。 The large energy and capital investment requirement provides the incentive for ongoing olefin-paraffin separation technology research。 A number of alternatives have been investigated。 The most promising one appears to be π-complexation and development of efficient π-complexation adsorbents has received increasing attention in recent years。

Two copper complexes [CuII2(O2CCH3)(OH)(OH2)(phen)2][BF4]2 ∙H2O (1) and [CuI2(bipy)2(OH2)2][BF4]2 (2) have been synthesized by using the reactant [CuI(CH3CN)4][BF4] and the ligands 2,2'-Dipyridyl and 1,10-Phenanthroline, and studied by X-ray single crystallography and intelligent gravimetric analyser。 Complex 1 shown the no existence property of ethylene-ethane separation due to the Cu (II) ions in molecule。 The number of the active sites in complex 2 is less, which leads to the poor property of ethylene-ethane separation。
