THE SEPERATION AND PURIFICATION METHOD OF 1,4-DIAMINOBUTANE FROM A FERMENTED SOLUTION

摘要

PURPOSE: A method for isolating and purifying 1,4-diaminobutane from a fermented solution is provided to obtain the 1,4-diaminobutane in high purity and yield. CONSTITUTION: A method for isolating and purifying 1,4-diaminobutane from a fermented solution comprises: a step of removing bacteria from a 1,4-diaminobutane fermentation solution; a step of adding a basic material to the bacteria-removed fermentation solution, and removing salt generated inside the solution; a step of concentrating the salt-removed fermentation solution; a step of removing impurities from the fermentation solution; and a step of collecting the 1,4-diaminobutane from the fermentation solution.
