Abstract
LA INVENCION SE REFIERE A MEZCLA DE OLIGOGLICERINA, QUE MUESTRA UN ALTO CONTENIDO EN DIGLICERINA, ELABORANDOSE DE FORMA QUE LA GLICERINA SE CONDENSA EN PRESENCIA DE ZEOLITAS DE LA FORMULA (I): M2/ZO * AL2O3 * XSIO2 * Y H2O, EN DONDE M ES UN METAL ALCALINO O ALCALINOTERREO DE VALENCIA Z, X ES UNA CIFRA DESDE 1,8 HASTA 12 E Y REPRESENTA CIFRAS DESDE 0 HASTA 8, ELIMINANDOSE EL AGUA DE CONDENSACION DE FORMA CONTINUA A PARTIR DE LA MEZCLA DE REACCION Y CON EMPOBRECIMIENTO DE REACCION, TAN PRONTO COMO HA SIDO SEPARADA LA CANTIDAD DE AGUA NECESARIA TEORICAMENTE PARA LA FORMACION DE DIGLICERINA. LAS ZEOLITAS SON INSOLUBLES EN LAS MEZCLAS DE REACCION Y PUEDEN SER SEPARADAS DESPUES DE LA REACCION SIN PROBLEMAS.
