Hydrogenolysis of the furan rings of furfural and furfuryl alcohol, which can be obtained from biomass, has attracted attention as a method for obtaining valuable chemicals such as 1,2-pentanediol. In this study, we examined the hydrogenolysis of furfuryl alcohol to 1,2-pentanediol over Pd/C, Pt/C, Rh/C, and various supported Ru catalysts in several solvents. In particular, we investigated the effects of combinations of solvents and supports on the reaction outcome. Of all the tested combinations, Ru/MgO in water gave the best selectivity for 1,2-pentanediol: with this catalyst, 42 % selectivity for 1,2-pentanediol was achieved upon hydrogenolysis of furfuryl alcohol for 1 h at 463 K. In contrast, reaction in water in the presence of Ru/Al₂O₃ afforded cyclopentanone and cyclopentanol by means of hydrogenation and rearrangement reactions.

负载型钌催化剂上糠醇氢解制1,2-戊二醇

可以从生物质中获得的糠醛和糠醇的呋喃环的氢解作为获得有价值的化学品（例如1,2-戊二醇）的方法而引起了人们的关注。在本研究中，我们研究了在几种溶剂中，Pd/C、Pt/C、Rh/C 和各种负载型 Ru 催化剂上糠醇氢解为 1,2-戊二醇的情况。特别是，我们研究了溶剂和载体的组合对反应结果的影响。在所有测试的组合中，Ru/MgO 水溶液对 1,2-戊二醇具有最佳选择性：使用该催化剂，糠醇在 463 K 下氢解 1 小时后，1,2-戊二醇的选择性达到 42%。相反，在Ru/Al ₂ O ₃存在下在水中的反应通过氢化和重排反应得到环戊酮和环戊醇。
