Abstract:
One aspect of the invention relates to a method for reducing salt content in an aqueous cadaverine salt composition comprising adjusting the pH of the aqueous cadaverine salt composition to provide a first composition comprising an aqueous cadaverine composition and a solid composition, wherein the pH of the aqueous cadaverine composition is at least about 12; and removing the solid composition from the first composition to provide the aqueous cadaverine composition. Another aspect of the invention relates to a method for the purification of cadaverine from an aqueous cadaverine salt composition using the salt-reducing method described herein; and obtaining cadaverine from the aqueous cadaverine composition.
