摘要： Catalysts, in particular clay catalysts, use in alkylation reaction of aromatic compounds, e.g., aromatic amines, that have lost activity during use, are regenerated by contacting the used catalyst with a mixture of a minor amount of an acid, in a mixture with water and an organic solvent. The regeneration process is readily incorporated into an alkylation process for aromatic amines.

摘要： Aromatic amines, for example, diarylamines such as diphenylamine, dinaphthylamine, N-phenyl-N-naphthyl amine etc., are alkylated by passing a mixture of the amine and an olefin, though a clay catalyst in a fixed bed reactor system. The process is conveniently run as a continued process, produces an alkylated aromatic amine in excellent purity and provides efficiencies in material and energy use.
