| synthesis and preparation methods | The first method: because the reaction between Aromatic halogen compounds and aromatic primary amines not only generates diaromatic amines, A Triarylamine is also produced, so that the reaction of p-iodotoluene and p-toluidine produces 4,4 '-dimethyldiphenylamine and simultaneously produces a large amount of 4,4',4 '-trimethyltriphenylamine. Second method: a method in which p-Toluidine is acylated, then reacted with P-iodotoluene, and finally hydrolyzed to prepare 4,4 '-dimethyldiphenylamine. This reaction makes up for the deficiency of the direct reaction of the Aromatic halogen compound with the aromatic primary amine, and the yield is low, but does not produce 4,4 ',4'-trimethyltriphenylamine. |
