Abstract
EN EL PROCEDIMIENTO PARA LA PREPARACION DE PIGMENTOS AZOICOS POR REACCION DE COPULACION AZOICA DE UN COMPONENTE DIAZOICO CON LA CANTIDAD EQUIVALENTE DE UN COMPONENTE DE COPULACION DIFICILMENTE SOLUBLE EN UNA SOLUCION ACUOSA ACIDA Y EN UNA SOLUCION ACUOSA NEUTRA A UNA TEMPERATURA INFERIOR A 65 GRADOS CENTIGRADOS, SE MEZCLA, EN UNA PRIMERA FASE DE REACCION Y DE MANERA CONTINUA, UNA SOLUCION ACUOSA ALCALINA DEL COMPONENTE DE COPULACION CON UNA SOLUCION ACUOSA DE UN ACIDO DEL GRUPO DEL ACIDO ACETICO, ACIDO BORICO, ACIDO FOSFORICO, ACIDO CLORHIDRICO O ACIDO SULFURICO, A UNA TEMPERATURA INFERIOR A 65 GRADOS CENTIGRADOS, EN UN INTERVALO DE TIEMPO INFERIOR A 1 MINUTO, CON LO QUE EL COMPNENTE DE COPULACION PRECIPITA, POR LO MENOS PARCIALMENTE, EN UNA FORMA REACTIVA, Y EN UNA SEGUNDA FASE DE REACCION QUE SIGUE INMEDIATAMENTE A LA PRIMERA, SE MEZCLA DE MANERA CONTINUA LA SUSPENSION FORMADA, CON UNA SOLUCION ACUOSA ACIDA DEL COMPONENTE DIAZOICO, A UNA TEMPERATURA INFERIOR A 65 GRADOS CENTIGRADOS, EN UN INTERVALO DE TIEMPO INFERIOR A 1 MINUTO, Y SE AJUSTA UN VALOR DE PH DETERMINADO COMPRENDIDO ENTRE 2 Y 9, MEDIANTE REGULACION DE LAS CORRIENTES MASICAS DEL COMPONENTE DIAZOICO Y DEL COMPONENTE DE COPULACION, CON LO QUE UNA PARTE DEL COMPONENTE DE COPULACION REACCIONA INMEDIATAMENTE PARA DAR EL PIGMENTO AZOICO DESEADO, MIENTRAS QUE EL RESTO NO REACCIONA PARA DAR EL PIGMENTO AZOICO DESEADO CON EL COMPONENTE DIAZOICO QUE TODAVIA NO HA REACCIONADO, MAS QUE EN UNA FASE DE REACCION SUBSIGUIENTE.
