开发D-葡萄糖异构化为D-果糖的催化工艺是提高木质纤维素原料价值的关键一步。本文综述了碱性催化剂作为高催化活性和容易商业化的分子和材料。最近的出版物报道，固体碱催化异构化主要是非均相的，只有一个小的贡献的催化OH-。对于胺的催化作用，氢氧离子相反地被认为是催化活性物质，尽管对D-果糖的选择性似乎取决于胺的结构。缓冲液是另一种可溶性碱性催化剂，它可以通过阴离子萃取或与苯基硼酸络合后的吸附，容易地与D果糖从反应混合物中的简单分离结合。
Development of a catalytic process for isomerization of D glucose into D-fructose presents a crucial step for valorization of lignocellulosic feedstocks. This review focuses on basic catalysts as highly catalytically active and readily commercially available molecules and materials. The recent publications report that the solid bases catalyze the isomerization mainly heterogeneously with only a minor contribution of catalysis by OH-. For catalysis by amines, the hydroxide ions are on the contrary believed to be catalytically active species, though selectivity for D-fructose seems to depend on the amine structure. Buffers present another type of soluble basic catalysts which can be readily coupled with a facile separation of D fructose from the reaction mixture via anionic extraction or adsorption upon complexation with phenylboronic acids.
