Reaction Conditions

Reaction Steps

288 parts of α-naphthol, 411 parts of p-phenetidine and 8 parts of tribenzyl phosphite are mixed and heated to 218° C. At this temperature, the elimination of water commences. The reaction temperature rises to 250° C in the course of 10 hours. At that stage, the reaction has ended and 36 parts of water have been removed. After removing excess p-phenetidine, the N-p-ethoxy-phenyl-α-naphthylamine distils at a boiling point of 233° - 235° C/5 mm Hg. 479 parts of end product of melting point 72° - 75° C are obtained. This corresponds to a yield of 91% of theory.
