Abstract
METODO PARA LA RECUPERACION Y ESTERIFICACION DE ANHIDRIDO MALEICO. UN METODO PARA LA RECUPERACION DE ANHIDRIDO MALEICO A PARTIR DEL EFLUENTE GASEOSO DE UN REACTOR DE OXIDACION Y, AL MISMO TIEMPO, LA ESTERIFICACION DEL ANHIDRIDO MALEICO. EN LA PRODUCCION DE ANHIDRIDO MALEICO A PARTIR DE BUTANO, EL PRIMERO ES EXTRAIDO DESDE EL EFLUENTE GASEOSO Y CONVERTIDO SIMULTANEAMENTE A UN ESTER DESEADO MEDIANTE LA REACCION CON UN ALCOHOL SELECCIONADO. SE PUEDE AGREGAR UN ACIDO PARA PRODUCIR PREFERIBLEMENTE EL DIESTER.
