【摘要】 生物基糠醛制备戊二醇的工艺相比于传统的石油基路线,具有原料来源广泛、生产过程绿色无污染等优点。本文总结了国内外以生物基糠醛为原料制备戊二醇的研究现状,并对应用于糠醛催化加氢制备戊二醇的铑、铱、铂、铜基催化剂分别进行了归纳整理,同时详细论述了两种糠醛氢解路线,即糠醛加氢分别以糠醇和四氢糠醇为中间体而氢解生成戊二醇的过程。在此基础上,提出了解决目前糠醛氢解制备戊二醇过程中存在的反应物浓度低、活性差、反应压力高等问题的建议。对未来从经济、环保等多角度出发设计并完善生物基戊二醇的生产工艺以及拓展高效利用生物基糠醛制备下游精细化工产品的方法做出了展望。为开发在温和条件下高效、稳定的催化生物基糠醛氢解的催化剂体系提供了参考。更多还原

【Abstract】 Compared to the traditional production of pentanediols from fossil resources,the production of pentanediols from biomass based furfural possessed various advantages such as the abundant raw materials and the green production process. In this paper,the status of the research on the production of pentanediols from biomass based furfural was discussed. A summary on the hydrogenation of furfural to pentanediols over rhodium,iridium,platinum and copper based catalysts was presented. Two kinds of reaction routes of furfural hydrogenolysis were also discussed. As a consequence,issues realated to the process of furfural hydrogenolysis,such as low reactant concentration,low reaction activity and quite high reaction pressure,were also presented. To design a process that is economical and environmental,the production techniques of pentanediols from biomass derived furfural hydrogenation were prospected in this paper. This review can be used for a reference in developing highly active catalytic system for the furfural hydrogenolysis under mild conditions.更多还原
