A highly efficient and green process was developed for direct conversion of levulinic acid into 1,4‐pentanediol over Mo‐modified Ru/activated carbon (AC) catalyst in a continuous fixed‐bed reactor. The Ru–MoO_x/AC catalyst was found to be efficient for the aqueous‐phase hydrogenation of levulinic acid to 1,4‐pentanediol, whereby a high yield (96.7 mol %) of 1,4‐pentanediol was obtained under mild reaction conditions (70 °C, 4 MPa H₂).

钼修饰的钌/活性炭催化剂上的丙戊酸加氢成1,4-戊二醇

开发了一种高效且绿色的工艺，用于在连续固定床反应器中，在Mo修饰的Ru /活性炭（AC）催化剂上将乙酰丙酸直接转化为1,4-戊二醇。发现Ru-MoO _x / AC催化剂可有效地将乙酰丙酸水相加氢为1,4-戊二醇，从而在温和的反应条件下可获得高产率（96.7 mol％）的1,4-戊二醇（70℃，4MPa H ₂）。
