Abstract:
A method for purifying 1,4-diaminobutane comprising the steps of: separating a second composition including carbonate salt of 1,4-diaminobutane from a first composition including carbonate salt of 1,4-diaminobutane by distillation; and removing carbonate from carbonate salt of 1,4-diaminobutane included in the second composition to recover 1,4-diaminobutane.
