Abstract

Procedimiento para la preparación de compuestos amino-azo-aromáticos, que especialmente comprende la diazotación de una amina aromática, copulación de la sal de diazonio con la mina aromática y psoterior reordenación del compuesto diazo-amino-aromático, caracterizado porque la reacción de diazotación se lleva a cabo con vapores nitrosos en un medio constituido esencialmente por la amina aromática, una sal de amina aromática y agua, en forma tal, que en cualquier instante, los porcentajes ponderales de estos tres compontes en el medio reaccional, que se designan respectivamente con alfa, beta y delta, cumplan las relación siguientes: 10<alfa<70 12<beta 5<delta alfa+beta+delta=100
