Abstract: PROCESS FOR THE PREPARATION OF ETHYLENE GLYCOL BY CATALYTIC HYDROGENATION A process for the preparation of ethylene glycol by the vapor phase catalytic hydrogenation of at least one of di(lower alkyl) oxalate and lower alkyl glycolate in the presence of a hydrogenation catalyst comprising a carrier, which catalyst is suitable for the hydrogenation of alkyl oxalate and alkyl glycolate to ethylene glycol, the improvement lies within the preparation of the catalyst by employment of catalysts comprising carriers having specific ranges of physical parameters, including average pore diameter and pore volume, which parameters are interrelated by a relative activity index.

Abstract: This invention relates to a process for selectively cleaving a polyalkylene glycol, e.g., diethylene glycol, containing at least one ether group therein at a carbon-to-oxygen covalent bond and independently at a carbon-to-carbon covalent bond by heating the polyalkylene glycol with molecular hydrogen in the presence of a hydrogenation catalyst containing ruthenium to produce at least one of monoethylene glycol monomethyl ether, monoethylene glycol and ethanol. The production rate of each of said monoethylene glycol monomethyl ether, monoethylene glycol and ethanol is at least about 10 moles/kilogram ruthenium/hour.
