摘要： A process for separating a homogeneous metathesis catalyst and, optionally, one or more homogeneous metathesis catalyst degradation products from a metathesis reaction mixture containing in addition to said metathesis catalyst and said metathesis catalyst degradation product(s), one or more olefin metathesis products, one or more unconverted reactant olefins, and optionally, a solvent. The process involves contacting the metathesis reaction mixture with a nanofiltration membrane, such as a polyimide nanofiltration membrane, so as to recover a permeate containing a substantial portion of the olefin reaction products, the unconverted reactant olefins, and optional solvent, and a retentate containing the metathesis catalyst, and optionally, metathesis catalyst degradation product(s). In another aspect, this invention pertains to a continuous metathesis reaction-catalyst separation process, preferably, conducted in a nanofiltration membrane reactor.
摘要翻译：一种用于从包含所述复分解催化剂和所述复分解催化剂分解产物的复分解反应混合物中分离均相复分解催化剂和任选的一种或多种均化复分解催化剂降解产物的方法，一种或多种烯烃复分解产物，一种或更多未转化的反应物烯烃，以及任选的溶剂。该方法包括使复分解反应混合物与纳滤膜如聚酰亚胺纳滤膜接触，以回收含有大部分烯烃反应产物，未转化反应物烯烃和任选溶剂的渗透物，以及含有复分解催化剂和任选的复分解催化剂降解产物。另一方面，本发明涉及连续复分解反应 - 催化剂分离方法，优选在纳滤膜反应器中进行。
