Abstract

SE SOMETE EL ACIDO ISOBUTIRICO A UNA OXIDESHIDROGENACION CATALITICA (ODH) EN FASE VAPOR (1), DANDO UNA MEZCLA (5) DE AGUA, DE ACIDO METACRILICO Y DE IMPUREZAS, CUYO ACIDO DE SALIDA NO ESTA CONVERTIDO ; SE CONDENSA LA MEZCLA (EN 6) Y SE REALIZA UNA EXTRACCION LIQUIDO-LIQUIDO (EN 8), PARA SEPARAR EL AGUA (EN 11) DE LOS ACIDOS ORGANICOS (10) ; (EN 21) SE ESTERIFIA ESTOS ACIDOS POR EL METANOL, DANDO UN MMA BRUTO, CON EL ISOBUTIRATO DE METILO COMO IMPUREZA. SE EXTRAE (EN 8) POR UNA FRACCION (9) DEL MMA BRUTO OBTENIDO ; SE ENVIA LA FASE (10) RESULTANTE A UNA ETAPA DE SEPARACION (22), SITUADA ABAJO DE LA ETAPA (21), PARA SEPARAR EL MMA BRUTO (23) (FRACCION DE MMA PRODUCIDO POR LA ESTERIFICACION Y LA UTILIZADA COMO SOLVENTE DE EXTRACCION), Y LOS ACIDOS ORGANICOS (24) (ACIDOS ORGANICOS OBTENIDOS POR EL ODH Y ACIDOS NO ESTERIFICADOS) ; SE PURIFICA (EN 33) LA FRACCION DE MMA BRUTO (32) NO UTILIZADA COMO SOLVENTE DE EXTRACCION, PARA SEPARAR DEL MMA PURO (EN 35) Y DEL ISOBUTIRATO DE METILO (34) RECICLADO EN (1).
