METHOD FOR PRODUCING XYLYLENEDIAMINE USING IMIDAZOLES AS SOLVENT

PROBLEM TO BE SOLVED: To provide a method for producing xylylenediamine, with which the used amount of ammonia is remarkably reduced and high-purity xylylenediamine is produced under a mild condition in a high yield. SOLUTION: In the method for producing xylylenediamine by mixing phthalonitrile with...

Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for producing xylylenediamine, with which the used amount of ammonia is remarkably reduced and high-purity xylylenediamine is produced under a mild condition in a high yield. SOLUTION: In the method for producing xylylenediamine by mixing phthalonitrile with a catalyst and a reaction solvent in an ammonia atmosphere and carrying out a hydrogenation reaction, an imidazole is used as the reaction solvent.
