Abstract

La invención se refiere a un proceso novedoso para la preparación de iminoestilbeno, mediante deshidrogenación, a alta temperatura, de iminodibencilo sobre un catalizador de contacto de óxido de hierro/sal de potasio, en fase de vapor, en donde se usa un catalizador de contacto de óxido de hierro/sal de potasio que comprende de 35 a 90 en peso de un compuesto de hierro, calculado como K2O, además de 0.0 a 3.5 en peso de un compuesto de cromo, calculado como Cr2O3 y los promotores usuales opcionales.
