The catalytic transfer hydrogenation (CTH) of glucose to sorbitol has been studied using a wide collection of different biomass-derived alcohols and diols as hydrogen donors. Catalytic activity results reflect the feasibility to conduct this transformation in the presence of conventional, commercially available Raney Ni-type sponges as catalysts. Sacrificial diols displayed a superior performance as hydrogen donors as compared to short-chain alcohols, including secondary alcohols. Among them, terminal diols such as 1,4-butanediol and 1,5-pentanediol were revealed as excellent hydrogen donors, providing a high selectivity in the conversion of glucose into sorbitol. As for the catalysts, molybdenum promotion provided a very high catalytic activity to sponge nickel catalysts, even under mild temperature conditions. The transformation was also studied in a fixed-bed reactor under continuous-flow operation conditions. Results demonstrate that the catalysts are highly stable and able to operate for at least 550 h on stream with a high selectivity in the CTH of glucose to sorbitol.

使用生物质衍生的二醇作为氢供体，用雷尼镍催化剂催化转移氢化葡萄糖为山梨糖醇
已经使用大量不同生物质衍生的醇和二醇作为氢供体研究了葡萄糖催化转移氢化 (CTH) 到山梨糖醇的过程。催化活性结果反映了在常规市售 Raney Ni 型海绵作为催化剂存在下进行这种转化的可行性。与包括仲醇在内的短链醇相比，牺牲二醇作为氢供体表现出优异的性能。其中，末端二醇如 1,4-丁二醇和 1,5-戊二醇被证明是优异的氢供体，在葡萄糖转化为山梨糖醇方面具有高选择性。至于催化剂，即使在温和的温度条件下，钼的促进也为海绵镍催化剂提供了非常高的催化活性。还在连续流动操作条件下在固定床反应器中研究了转化。结果表明，该催化剂高度稳定，并且能够以高选择性在葡萄糖到山梨糖醇的 CTH 中运行至少 550 小时。
