糖醇催化氢解制低级多元醇研究进展

利用糖醇生产低级多元醇可以减少对石油资源的依赖，是可再生资源利用的一个重要研究方向。本文综述了利用糖醇为原料催化氢解制备低级多元醇的研究成果，氢解糖醇可以高选择性得到乙二醇、丙三醇和1,2-丙二醇的混合物。重点介绍了糖醇催化氢解的Retro-aldol、 Retro-Michael反应机理和铜系、镍系、贵金属催化剂，并对糖醇催化氢解的发展前景做了展望，提出开发更为高效稳定的催化体系、降低催化剂制备成本和优化工艺条件将是未来研究工作的重点。

Advances in the production of lower polydric alcohols by catalytic hydrogenolysis of sugar and sugar alcohols

With the diminishing resources of fossil fuels，searching for sustainable，alternative energy is critically important. In this paper，the recent advances in catalytic hydrogenolysis of sugar alcohols to lower polydric alcohols are reviewed. Ethylene glycol，glycerol，1,3-propylene glycol could be obtained with high selectivity by hydrogenolysis of sugar alcohols. Emphases are laid on the Retro-aldol，Retro-Michael reaction mechanisms and copper，nickel，noble metal based catalysts for the hydrogenolysis of sugar alcohols. The review shows that the future research should be focused on the development of more effective and stable catalysts，the cost reduction for catalysts preparation and the optimization of processing condition.
