    • A process of stabilizing an olefin metathesis product mixture, preferably, against double bond isomerization and thermal and chemical degradation. The process involves (a) contacting an olefin metathesis product mixture comprising one or more olefins produced in a metathesis process, a metathesis catalyst comprising a catalytic metal and one or more ligands, optionally, one or more metathesis catalyst degradation products, and optionally, one or more metals derived from sources other than the catalyst or catalyst degradation product(s), with an adsorbent, more preferably carbon; or alternatively, (b) subjecting the olefin metathesis product mixture to a two-step distillation, preferably, including short path wiped-film evaporation. A stabilized olefin metathesis product mixture to a two-step distillation, preferably, including short path wiped-film evaporation. A stabilized olefin metathesis product mixture is disclosed containing one or more olefins obtained in a metathesis process and having a total concentration of metal(s) of less than about 30 parts per million by weight.
    • 稳定烯烃复分解产物混合物的方法,优选地防止双键异构化和热和化学降解。 该方法包括(a)使包含以复分解方法生产的一种或多种烯烃的烯烃复分解产物混合物,包含催化金属和一种或多种配体,任选的一种或多种复分解催化剂降解产物的复分解催化剂和任选的一种 或更多来自除催化剂或催化剂分解产物之外的来源的金属,具有吸附剂,更优选碳; 或者(b)使烯烃复分解产物混合物进行两步蒸馏,优选包括短路擦拭膜蒸发。 将稳定的烯烃复分解产物混合物进行两步蒸馏,优选包括短路径擦拭膜蒸发。 公开了一种稳定的烯烃复分解产物混合物,其含有一种或多种以复分解方法获得的烯烃,其总金属浓度小于约30重量ppm。
