    • One aspect of the invention relates to a method for the purification of cadaverine from an aqueous cadaverine composition comprising one or more involatile impurities, the method comprising obtaining cadaverine from evaporation or distillation of the aqueous cadaverine composition wherein one or more solvents are added to the evaporation/distillation system before the evaporation/distillation starts, during the evaporation/distillation and/or after the evaporation/distillation substantially stops when no more evaporation/distillation is observed; wherein the one or more solvents comprise at least one or more high boiling point (HBP) solvents. In certain embodiments, cadaverine may be evaporated/distilled at an unexpectedly lower heating temperature for an unexpectedly shorter heating time to provide a desired yield. Because cadaverine may decompose at high temperature, the unexpectedly lower heating temperature and unexpectedly shorter heating time decrease the undesired cadaverine decomposition. The methods disclosed herein provides unexpected high recovery rate (~100%) in the evaporation/distillation of cadaverine at a larger scale at a lower heating temperature compared to conventional distillation methods. Thus, the method disclosed herein will be highly appreciated in the industrial production of cadaverine.
    • 本发明的一个方面涉及从包含一种或多种非挥发性杂质的水性尸胺组合物中纯化尸胺的方法,所述方法包括从蒸发或蒸馏水性尸胺组合物中获得尸胺,其中将一种或多种溶剂加入蒸发 在蒸发/蒸馏开始之前,蒸发/蒸馏期间和/或蒸发/蒸馏之后蒸馏/蒸馏系统在不再观察到蒸发/蒸馏的情况下基本停止; 其中所述一种或多种溶剂包含至少一种或多种高沸点(HBP)溶剂。 在某些实施方案中,可以在意想不到的较低加热温度下将尸胺蒸发/蒸馏,以期意外地更短的加热时间以提供所需的产率。 因为尸体可能会在高温下分解,出人意料地降低加热温度,而且意外的加热时间会缩短,从而减少不希望的尸体分解。 与常规蒸馏方法相比,本文公开的方法提供了在比较低的加热温度下较大规模的尸胺蒸发/蒸馏中意想不到的高回收率(〜100%)。 因此,本文公开的方法将在尸胺的工业生产中被高度赞赏。
