    Abstract: Cuprous organohaloaluminates and cuprous organohaloborates possessing the general formula CuMRX3 wherein M is a boron or aluminum atom, X is a chlorine, bromine or fluorine atom, and R is a monovalent lower alkyl radical, phenyl radical, alkylaryl radical or substituted alkyl phenyl or alkylaryl radical, readily complex with olefins, diolefins, acetylenes, aromatics, carbon monoxide, etc. The cuprous organohaloaluminates and cuprous organohaloborates are employed in the separation and recovery of complexible ligands from feedstreams containing the same. Typically, a feedstream containing a complexible ligand is contacted with a liquid sorbent system comprising the cuprous organohaloaluminate and/or cuprous organohaloborate. The complexible ligands contained in the feedstream complex with the organometal compositions and are ultimately recovered therefrom by a ligand exchange operation generally requiring n-l ligand exchange operations for n complexed complexible ligands to be separated and recovered. The separation in each of the ligand exchange operations is accomplished by contacting the organometal-complexible ligand complex with a stripping ligand that forms a more stable complex with the organometallic material than the complexible ligand or ligands, thereby exchanging the stripping complexible ligand or ligands in the original sorbent complex.

    Abstract translation: 具有通式CuMRX3的铜有机卤代铝酸盐和有机卤硼酸盐，其中M为硼或铝原子，X为氯，溴或氟原子，R为一价低级烷基，苯基，烷基芳基或取代的烷基苯基或烷基芳基 与烯烃，二烯烃，乙炔，芳族化合物，一氧化碳等容易复合。有机卤代铝和有机卤代硼酸盐用于从含有它们的原料流中分离和回收可络合的配体。 通常，含有可络合配体的进料流与包含有机卤铝酸钠和/或有机卤代硼酸盐的液体吸附剂体系接触。 包含在与有机金属组合物的进料流络合物中的可络合配体通过配体交换操作最终从其中回收，通常需要n络合的可络合配体的n-1配体交换操作来分离和回收。 每个配体交换操作中的分离是通过使有机金属络合物配体与剥离配体接触来实现的，所述剥离配体与有机金属材料形成比可络合的配体或配体更有稳定的络合物，由此将剥离的可络合配体或配体交换在 原始吸附剂复合物。
