Abstract
SE PRESENTA UN PROCESO PARA LA PRODUCCION DE PENTOXIDO DE DINITROGENO (N{SUB, 2}O{SUB, 5}) EN UN SOLVENTE ORGANICO QUE CONSTA DE LA DIVISION DE UNA MENOR PROPORCION (31) DE UNA CORRIENTE DE UN COMPUESTO DE ANODO (11) DE UNA PILA ELECTROLITICA (2) QUE SE DISPONE PARA GENERAR N{SUB, 2}O{SUB, 5} Y EN EL ENFRIAMIENTO DE ESA PARTE Y/O LA ADICION A ESA PARTE DE UNA CANTIDAD DE N{SUB, 2}O{SUB, 4}, DE MANERA QUE SE FORMEN DOS FASES. LAS FASES SE SEPARAN (34) Y LA FASE LIGERA (SUPERIOR) DE N{SUB, 2}O{SUB, 4} SE SEPARA DEL N{SUB, 2}O{SUB, 5} DISUELTO, EL N{SUB, 2}O{SUB, 5} SE VUELVE A DISOLVER EN UN SOLVENTE ORGANICO. CONVENIENTEMENTE, LA FASE DE N{SUB, 2}O{SUB, 4} SE CONGELA (EN 41) PARA PRODUCIR N{SUB, 2}O{SUB, 5} CRISTALINO QUE SE DISUELVE EN UN SOLVENTE ORGANICO TAL COMO EL DICLOROMETANO. TODAS LAS CORRIENTES EFLUYENTES PUEDEN RECICLARSE CON LA ADICION SOLAMENTE DE ACIDO NITRICO NUEVO, CONCENTRADO, Y EL N{SUB, 2}O{SUB, 4} NUEVO PARA HACER EL PROCESO CAPAZ DE UN FUNCIONAMIENTO CONTINUO.
