Abstract
UN PROCESO PARA CRISTALIZAR EL INGREDIENTE DE BISFENOL A CON FENOL DE UNA DISOLUCION FENOL EN LA PRESENCIA DE AGUA COMPRENDE CONTROLAR LA CONCENTRACION DE BISFENOL A EN DICHA DISOLUCION POR ELIMINACION DE PARTE DEL FENOL DE DICHA DISOLUCION O ADICION DE FENOL A DICHA DISOLUCION DE ACUERDO A UN CONTROL DE REALIMENTACION BASADO EN LA MEDIDA DE LA DENSIDAD DE LA DISOLUCION OBTENIDA EN LA DISOLUCION AJUSTADA, Y SUMINISTRAR LA DISOLUCION AJUSTADA AL CRISTALIZAR EN EL QUE SU PARED INTERIOR ES MANTENIDA A UNA TEMPERATURA MAYOR QUE LA DE LA DISOLUCION AJUSTADA, PROVISTA LA DIFERENCIA DE TEMPERATURA MENOR DE 5 C. EL INGREDIENTE CRISTALIZADO TIENE UN TAMAÑO DE PARTICULA UNIFORME Y UNA ALTA PUREZA.
