Abstract
I metalli nobili rutenio, rodio, palladio e platino supportati su allumina, silice, silice-allumina e magnesia (Mgo) sono in grado di convertire i carbonati organici ad eteri.La produzione di eteri e/o polieteri, specialmente di alchileteri secondo il processo dell'invenzione, evita l'uso di agenti alchilanti organici quali gli alogenuri CH3C1 e i solfati alchilici (CH3)2SO4.Gli eteri prodotti trovano la stessa applicazione degli eteri dell'arte nota e prodotti per altra via.Trovano soprattutto impiego quali solventi speciali.
