摘要: 传统的以石油化工产品为原料的石化基1,6-己二醇(1,6-HDO)的生产存在能耗高、反应产物分离困难、污染环境等缺点,以5-羟甲基糠醛(5-HMF)为原料制备生物基1,6-HDO可以克服这些缺点。本文介绍了国内外制备生物基1,6-HDO的研究进展,总结并讨论了由5-HMF制备1,6-HDO的不同反应路径,并从反应物吸附、金属粒径、活性组分协同作用、载体等角度对比了不同催化剂体系及其催化机理,探讨了各种催化剂促进C=O加氢、呋喃环C=C加氢、呋喃环C—O氢解开环反应,抑制呋喃环、呋喃环侧链C—C氢解断裂反应的性能。与多步法相比,一步法制备1,6-HDO的反应步骤简单,但1,6-HDO的产率相对较低,因此开发高效的催化剂体系和反应工艺将是今后研究的重点。

Abstract: Conventional production of 1,6-hexanediol (1,6-HDO) with petrochemicals,has disadvantages of high energy consumption,product separation difficulties and environmental contamination. These limitations can,to some extent,be overcome by biorefinery process,especially that of 5-HMF based. The status quo of production of biobased 1,6-HDO was summarized,and different reaction pathways for conversion of 5-HMF to 1,6-HDO was discussed. This review compared different catalysts and catalytic mechanisms in respect of adsorption of reagent,metal particle size,synergistic interaction,and support. The catalyst performance in promoting hydrogenation of C=O,hydrogenation of furan ring,and hydrogenolysis of C—O,yet restraining hydrogenolysis of C—C were also investigated. Compared with multistep reactions,one-step reaction was simpler but with lower 1,6-HDO production. Therefore,developing more efficient catalyst and process will be the focus of future research.
