Abstract

La presente invención se refiere a procedimiento para acoplar uno ovarios diazocomponentes diferentes con resorcina, donde se prepara una solución acuosa de resorcina en un recipiente de reacción, se ajusta el valor de pH deceado para el acoplamiento y se deja afluir en forma separada a) la solución de ácido mineral del diazocomponente diazotizado o bien sucesivamente las soluciones de ácidos minerales de los diferentes diazocomponentes diazotizados y b) la solución de una base, el procedimieno está caracterizado porque la(s) reacción(es) de acoplamiento se lleva a cabo en forma adiabática y el valor de pH de acoplamiento del recipiente con la resorcina se ajusta y estabiliza antes de la reacción con un sistema buffer (amortiguador) y durante la(s) reacción(es) de acoplamiento se mantiene constante por medio de una regulación de las proporciones de circulación de las afluencias a) y b).
