摘要
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.
