Claim Text:
1. A process for making a hydroxy mono-ether compound, comprising: feeding a cyclic acetal or cyclic ketal compound and hydrogen, without feeding a carbonyl compound, into a reaction vessel; reacting the cyclic acetal or cyclic ketal compound with the hydrogen in the presence of (i) a noble metal catalyst supported on carbon or silica and (ii) a solvent comprising a polyhydroxyl compound used to make the cyclic acetal or cyclic ketal compound, to form a hydroxy mono-ether compound, wherein the reaction is carried out in the absence of an added acidic co-catalyst or promoter, and wherein the molar ratio of the polyhydroxyl compound to the cyclic acetal or cyclic ketal compound is at least 2:1.
