摘要:
An improved 2,6-dialkylaniline process carried out by reacting an aromatic amine having an unsubstituted ortho position with an olefin in the presence of an aluminum anilide type catalyst followed by catalyst deactivation and distillation to remove 2,6-dialkylaniline. The distillation residue is catalytically hydrogenated and then distilled to recover additional 2,6-dialkylaniline.
