Abstract

CE PROCEDE EST CARACTERISE PAR LE FAIT QUE LE DIMETHYLETHER EST FORME EN PRESENCE D'UNE COMPOSITION CATALYTIQUE CONSTITUEE GLOBALEMENT PAR: A.UNE SILICE CRISTALLINE DANS LAQUELLE CERTAINS ATOMES DE SILICIUM DANS LE RESEAU CRISTALLIN SONT REMPLACES PAR L'ALUMINIUM, ET QUI CORRESPOND A LA FORMULE GENERALE:ISI (0,0012-0,0050)AL OYOU Y VARIE ENTRE 2,0018 ET 2,0075; B.UN MELANGE DES OXYDES ETOU DE SELS DE CU, ZN, CR OU DE CU, ZN, AL, AL POUVANT ETRE EGALEMENT PRESENT EN MEME TEMPS QUE LE CR. UTILISATION DE CE PROCEDE POUR PREPARER LE DIMETHYLETHER A DES TEMPERATURES BEAUCOUP PLUS BASSES QUE DANS LES PROCEDES DE L'ART ANTERIEUR.
