Abstract
Provided is a method of refining 1,5-diaminopentane, the method including preparing a fermented broth including a carbonate salt of 1,5-diaminopentane; preparing a first composition by heating the fermented broth; preparing a second composition and an evaporation residue by evaporating the first composition; preparing a third composition by adding water to the evaporation residue and evaporating the water; and recovering 1,5-diaminopentane by distilling the second composition and the third composition.
Claims8
A method of refining 1,5-diaminopentane, the method comprising:
- preparing a fermented broth comprising a carbonate salt of 1,5-diaminopentane;
- preparing, by heating the fermented broth, a first composition in which the carbonate salt of 1,5-diaminopentane is thermally decomposed;
- preparing a second composition and an evaporation residue by evaporating the first composition;
- preparing a third composition by adding water to the evaporation residue and evaporating the water;
- and
- recovering 1,5-diaminopentane by distilling the second composition and the third composition.
