Abstract

Procedimiento para preparar una suspensión acuosa de un compuesto azóico insoluble en agua, caracterizado porque comprende reaccionar conjuntamente en forma contínua, en una zona de reacción de la cual se separa continuamente la suspensión, una primera corriente que contiene un compuesto de diazonio resultante de la diazotación de una amina benzenoide débilmente básica o heterocíclica en un medio ácido, el cual se denomina a continuación como componente diazoico, y una segunda corriente que contiene un compuesto capaz de copularse con el componente diazoico bajo las condiciones que existen en la zona de reacción para formar un compuesto azóico insoluble en agua, el cual se llamará a continuación componente de copulación.
