摘要：
A purification method of 1,4-diaminobutane, 1,4-diaminobutane purified using the purification method, and a polyamide prepared using the purified 1,4-diaminobutane are provided. The purification method of 1,4-diaminobutane includes: concentrating a fermentation solution including at least one of 1,4-diaminobutane and a salt thereof to obtain a concentrate; adding a base to the concentrate of the fermentation solution to prepare an basic composition having a pH 12 or higher; and recovering 1,4-diaminobutane from the basic composition.
