Estimating the term…
The present invention relates to a process for producing hydrogenolysis products of polyhydric alcohols with a good selectivity and a high yield, as well as hydrogenolysis catalysts used in the production process. The present invention provides (1) a process for producing a hydrogenolysis product of a polyhydric alcohol which includes the step of reacting the polyhydric alcohol with hydrogen in the presence of a catalyst containing a copper component, wherein the catalyst is a catalyst (A) containing the copper component, an iron component and an aluminum component, or a catalyst (B) containing the copper component and a silicon component; and (2) a hydrogenolysis catalyst for polyhydric alcohols which includes a copper component, an iron component and an aluminum component, and (3) a hydrogenolysis catalyst for polyhydric alcohols which includes a copper component and a silicon component.
A process for producing a hydrogenolysis product of a polyhydric alcohol, comprising reacting the polyhydric alcohol with hydrogen in the presence of a catalyst containing a copper component, wherein the catalyst is a catalyst (B) comprising the copper component and a silicon component, and wherein said reacting is in a liquid phase.
