Abstract: The present invention provides a process for the hydrogenation of the levulinic acid to γ-valerolactone in a single step with a single Pt supported on hydrotalcite catalyst. The process provides conversion of γ-valerolactone over Pt supported hydrotalcite catalyst at room temperature (25° C.). The process provides a levulinic acid conversion of 34-100% with 20-50 bar hydrogen pressure to give γ-valerolactone selectivity up to 99%.
Abstract translation: 本发明提供了在单一步骤中将乙酰丙酸氢化为γ-戊内酯的方法，其中单一Pt负载在水滑石催化剂上。 该方法在室温（25℃）下提供γ-戊内酯与Pt负载的水滑石催化剂的转化。 该方法在20-50巴氢压下提供34-100％的乙酰丙酸转化率，得到高达99％的γ-戊内酯选择性。
