Abstract
UN PROCESO PARA PREPARAR LACTUOSA DE LACTOSA EN EL CUAL, UNA MEZCLA DE LACTOSA ACUOSA SE HACE REACCIONAR CON UNA DISOLUCION DE ALUMINATO DE SODIO Y LA DISOLUCION OBTENIDA ES NEUTRALIZADA CONTINUAMENTE POR EL SUMINISTRO DE ESTA DISOLUCION Y UNA DISOLUCION DE ACIDO SULFURICO A UN REACTOR SIMULTANEAMENTE DE TAL MANERA QUE SE OBTIENE UN PH ENTRE 4.5 Y 8. POR OPERAR DE ESTA MANERA SE OBTIENE UN HIDROXIDO DE ALUMINIO QUE PUEDE SER FACILMENTE SEPARADO DE LA DISOLUCION LACTUOSA.
