Abstract
SE DESCRIBE UN PROCESO PARA LA PRODUCCION DE GAMMA BUTIROLACTONA (GBL) SUSTANCIALMENTE PURA A PARTIR DE UNA MEZCLA DE ALIMENTACION QUE CONTIENE UNA CANTIDAD IMPORTANTE DE GBL Y UNA CANTIDAD SECUNDARIA DE SUCCINATO DE DIETILO (SDE), QUE COMPRENDE LA DESTILACION FRACCIONADA DE LA MEZCLA EN UNA ZONA DE FRACCIONAMIENTO EN PRESENCIA DE ETOXISUCCINATO DE DIETILO (ESDE), Y RECUPERAR DE DICHA ZONA DE FRACCIONAMIENTO UN PRODUCTO DE CABEZA EN FORMA DE VAPOR, QUE CONTIENE GBL SUSTANCIALMENTE LIBRE DE SDE Y UN PRODUCTO DE COLA LIQUIDO QUE CONTIENE UNA MEZCLA DE ESDE Y SDE. EL PROCEDIMIENTO SE PUEDE EMPLEAR PARA SEPARAR UNA FRACCION RICA EN GBL OBTENIDA POR DESTILACION EN UNA O VARIAS ETAPAS DE UN PRODUCTO DE REACCION CRUDO OBTENIDO POR HIDROGENACION DE UN PRODUCTO DE PARTIDA A BASE DE ESTER DE UN ACIDO DICARBOXILICO DE 4C, QUE CONTIENE UNA CANTIDAD MOLAR IMPORTANTE DE MALEATO DE DIETILO (MDE) Y UNA CANTIDAD PEQUEÑA DE SDE, UTILIZANDO UNA ALIMENTACION DE MDE PARA EL PROCESO DE HIDROGENACION, LA CUAL SE MEZCLA CON SDE RECUPERADO DE LA ZONA DE FRACCIONAMIENTO.
