从发酵溶液分离和纯化1,4-二氨基丁烷的方法
摘要：
本发明的名称为从发酵溶液分离和纯化1,4‑二氨基丁烷的方法。本发明涉及通过细胞团去除、脱盐、浓缩、杂质去除和回收而从包括1,4‑二氨基丁烷的发酵溶液以高纯度和高产率分离和纯化1,4‑二氨基丁烷的方法。还提供通过细胞团去除、脱盐、低温浓缩、结晶、过滤、高温浓缩和蒸馏而从包括1,4‑二氨基丁烷的发酵溶液以高纯度和高产率分离和纯化1,4‑二氨基丁烷的方法。
摘要（英）：

The present invention relates to a method for separating and purifying 1,4-diaminobutane of a high purity and high yield from a 1,4-diaminobutane fermented solution, produced by fermentation, throughthe steps of strain separation, salt removal, concentration, removal of impurities, and recovery. In addition, the present invention relates to a method for separating and purifying 1,4-diaminobutaneof a high purity and high yield from a 1,4-diaminobutane fermented solution, produced by fermentation, through the steps of strain separation, salt removal, low temperature concentration, crystallization, filtration, high temperature concentration, and distillation.
