    • The present invention is directed to compositions and methods for the recovery of olefins from a mixture. The compositions of the present invention comprise: (1) a transition metal ion; (2) a counter anion; (3) a ligand selected from the group consisting of a bidentate ligand and a tridentate ligand, wherein the ligand comprises at least two nitrogen atoms, and wherein each of the nitrogen atoms comprises a lone pair of electrons; and (4) a polar solvent with a boiling point of at least about 200 0C. The methods of the present invention comprise: (1) providing the aforementioned compositions; (2) bonding at least a portion of the olefins in a mixture to the transition metal ion in the composition to form a complex; (3) separating the complex from the mixture; and (4) recovering the olefins from the complex.
    • 本发明涉及从混合物中回收烯烃的组合物和方法。 本发明的组合物包含:(1)过渡金属离子; (2)抗衡阴离子; (3)选自二齿配体和三齿配体的配体,其中所述配体包含至少两个氮原子,并且其中每个氮原子包含一对电子; 和(4)沸点至少约为200℃的极性溶剂。 本发明的方法包括:(1)提供上述组合物; (2)将组合物中的至少一部分烯烃与混合物中的过渡金属离子结合以形成络合物; (3)将混合物与混合物分离; 和(4)从络合物中回收烯烃。
