PROCESS FOR PREPARING ALIPHATIC ALPHA,OMEGA-AMINONITRILES.

摘要

Aliphatic alpha,omega-aminonitriles are prepared by partially hydrogenating aliphatic alpha,omega-dinitriles at an increased temperature and pressure in the presence of a base and an hydrogenation catalyst. Hydrogenation is carried out in the presence of ammonia and lithium hydroxide or a compound that releases lithium hydroxide during the hydrogenation process.
