A method for the production of diarylmethane derivatives, dibenzyl amines

摘要

The invention relates to a process for the preparation of dibenzylamine through hydrogenation of benzaldehyde in the presence of ammonia and a Pd-containing catalyst. With the method according to the invention, dibenzylamine can be prepared with a high selectivity in a relatively short reaction time, and upon complete conversion of the benzaldehyde. In addition, a particularly attractive commercial Procedure appears to be possible. In the process according to the invention is preferably is made of a Pd / C-catalyst.
