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.
本发明涉及一种醛缩酮缩环化合物的液相加氢解反应。将醛缩酮缩环化合物送入反应区,在碳或二氧化硅载体上的贵金属催化剂存在下反应,高选择性地制得羟基单醚化合物,无需使用含磷酸或稳定剂(如氢醌)的酸性辅助催化剂。
