A catalytic dehydrogenation of alkylene glycol ether to ether ketone or aldehyde is disclosed. The dehydrogenation is performed with copper chromite catalyst and at least 5 wt % of water based on alkylene glycol ether. It has been found that the selectively to formation of ether ketone or aldehyde increases with increasing the amount of water in the alkylene glycol ether.
L'invention concerne la déshydrogénation catalytique d'éther d'alkylèneglycol en éther cétonique ou en aldéhyde. On utilise pour la déshydrogénation un catalyseur de chromite de cuivre bivalent et au moins 5 % en poids d'eau, en fonction de la quantité d'éther d'alkylèneglycol. On a remarqué que la sélectivité vis à vis de l'éther cétonique ou de l'aldéhyde augmente avec la quantité d'eau contenue dans l'éther d'alkylèneglyvol.
