Abstract
A liquid phase hydrogenolysis of acetal compounds, such as cyclic acetals and cyclic ketals, is disclosed. The acetal compounds are fed to a reaction zone and reacted in the presence of a noble metal catalyst supported on a carbon or silica support to make hydroxy mono-ether compounds in high selectivity, without the necessity of using acidic co-catalysts such as phosphorus containing acids or stabilizers such as hydroquinone.
