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 SOLUCIONES ACUOSAS ACIDAS Y ACUOSAS NEUTRAS A UNA TEMPERATURA INFERIOR A 65 GRADOS CENTIGRADOS, SE MEZCLA CONTINUAMENTE UNA SOLUCION ACUOSA ACIDA DE LOS COMPONENTES DIAZOICOS CON LA SOLUCION ACUOSA ALCALINA DE LOS COMPONENTES DE COPULACION, 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 ENTRE 2 Y 9, MEDIANTE REGULACION DE LAS CORRIENTES MASICAS DE LOS COMPONENTES DIAZOICOS Y DE LOS COMPONENTES DE COPULACION, CON LO QUE UNA PARTE DE LOS COMPONENTES DE COPULACION REACCIONAN INMEDIATAMENTE PARA DAR EL PIGMENTO AZOICO DESEADO, MIENTRAS QUE, AL MISMO TIEMPO, EL RESTO DE LOS COMPONENTES DE COPULACION PRECIPITA EN UNA FORMA REACTIVA Y FINAMENTE CRISTALIZADA, Y NO REACCIONAN CON LOS COMPONENTES DIAZOICOSQUE TODAVIA NO HAN REACCIONADO HASTA UNA FASE DE REACCION POSTERIOR, PARA DAR LOS PIGMENTOS AZOICOS DESEADOS.
