Cyanoethylation of aromatic amines |
摘要 |
An improved process is disclosed for the production of cyanoethylated aromatic amines comprising contacting an aromatic amine with acrylonitrile in the presence of a silica-alumina catalyst in a liquid phase reaction at elevated temperature. Aromatic polyamines are cyanoethylated according to the process of this invention to form a reaction product comprising poly-(N-monocyanoethylated) aromatic amines and poly-(N-monocyanoethylated) aromatic amines additionally having at least one cyanoethyl group attached to the nucleus of the aromatic ring.
