Procedure

The aforementioned concentrate was cooled from 60° C. to 10° C. at 4° C./hour to precipitate crystals. The crystallization rate was 40 to 45%. The precipitated crystals were separated and collected using a centrifuge and air-dried in a desiccator for several days. When the obtained crystals were analyzed by X-ray crystallography (AFC-5S produced by Rigaku Corporation, analytical program: TEXAN), they were found to consist of cadaverine adipate dihydrate, and the purity was 99% or higher. These crystals contain cadaverine and adipic acid in equimolar amounts and can be used for a polymerization reaction of nylon as is.
