Abstract

EL INVENTO SE REFIERE A UN PROCEDIMIENTO QUE SE UTILIZA PARA OBTENER COLORANTES MONO Y POLIAZO DE GRAN CALIDAD Y CON ELEVADO RENDIMIENTO. CONSISTE EN COPULAR UNO O VARIOS COMPONENTES DIFERENTES DIAZO CON RESORCINA Y SE CARACTERIZA PORQUE SE AJUSTA EL VALOR DEL PH DE COPULACION DE LA MUESTRA DE RESORCINA CON UN SISTEMA TAMPON; SE ESTABILIZA DICHA MUESTRAS, SE REGULA LA COPULACION SEGUN LA RELACION DEL FLUJO DE ENTRADA DEL COMPONENTE DIAZO Y SE MANTIENE LA BASE CONSTANTE.
