Acid catalyzed pressure synthesis of N,N‐dimethylbenzylamine from benzylamine and methanol

Abstract

The synthesis of N,N‐dimethylbenzylamine from benzylamine and methanol in the presence of hydrochloric acid catalyst has been carried out under pressure. Nitrogen pressure is helpful only to a limited extent, beyond which it is neither helpful nor detrimental. Under optimum conditions (517 K, 6.0295 MPa, residence period 2 h, benzylamine‐to‐methanol‐to‐hydrochloric acid mol ratio 1:2:1) the conversion of benzylamine to N,N‐dimethylbenzylamine is 57.09%.
