Abstract
PARA LA MANUFACTURA DE LACTULOSA, UNA SOLUCION ACUOSA ALCALINA DE LACTOSA Y BORAX ES PREPARADA Y CALENTADA A UNA TEMPERATURA SUPERIOR A 80 C. LA LACTULOSA ES SEPARADA DE LOS PRODUCTOS DE CONVERSION RESULTANTES. APARTE DEL BOROX, NINGUN MATERIAL ALCALIZADOR ES AÑADIDO A LA SOLUCION. LA CONVERSION ES REALIZADA A PH 8.3. EN ORDEN PARA MANTENER LOS IONES DE SODIO EN EL CICLO DE PRODUCCION, EL BOROX DEBE SER MANUFACTURADO EN UNA SOLUCION ACUOSA DE ACIDO BORICO Y SIMULTANEAMENTE CON LA LACTOSA, MIENTRAS LOS IONES DE SODIO SON TRANSFERIDOS DESDE LA SOLUCION DE LOS PRODUCTOS DE CONVERSION EN LA SOLUCION DEL ACIDO BORICO POR ELECTRODIALISIS. ALTERNATIVAMENTE LOS IONES DE SODIO DEBEN SER QUITADOS DE LA SOLUCION DE LOS PRODUCTOS DE CONVERSION TAN RAPIDAMENTE COMO SEA POSIBLE POR MEDIO DE UN CAMBIADOR DE ION DE ACIDO DEBILMENTE Y SOLAMENTE DESPUES DE ELLO POR MEDIO DE UN CAMBIADOR DE ION DE ACIDO MAS FUERTEMENTE. EL CAMBIADOR DE ION DE ACIDO DEBILMENTE ES REGENERADO CON ACIDO BORICO PARA QUE EL BORAXSE FORME DE NUEVO.
