Abstract:
The present invention relates to a method for separating and purifying 1,4-diaminobutane at high purity and high yield from a fermented solution comprising 1,4-diaminobutane, through cell mass removement, desalination, concentration, impurities removal, and recovery. Also, provided is a method for separating and purifying 1,4-diaminobutane at high purity and high yield from a fermented solution 1,4-diaminobutane, through cell mass removement, desalination, low-temperature concentration, crystallization, filtration, high-temperature concentration and distillation.
