PROCESS FOR PREPARATION OF AMINO BENZYLAMINE

摘要

Amino benzylamine is prepd. by catalytic redn. of nitro benzylamine isomers (ortho, meta and para-, obtd. by nitration of benzylamine) in the presence of Pt gp. metal. Add O-nitro benzylamine 13.6g, MeOH 50 ml and 5% pd/c catalyst 0.3g into glassware and cover tightly, vigorously stir for 3 hrs at 30-40 deg.C with inject H2 into rxn. container, filter and vacuum distillate to give 10.1g of aminobenzylamine (yield=82.7 %).
