Abstract
An improved method for making alkylated aromatic amines is disclosed. The method includes a new alkylating catalyst system comprising an aromatic amine alkylating catalyst and a non-catalyst solid such as silica. The method results in faster reaction rates and higher yields of alkylated aromatic amines.
