碳水化合物有效转化成5-羟甲基糠醛的绿色催化方法
摘要：
本发明涉及一种由碳水化合物临水温和条件下，有效转化到5‑羟甲基糠醛的多相催化体系。以碳水化合物为原料，离子液体功能化生物质炭磺酸（BC‑SO3H‑IL‑X，X=CF3SO3‑、BF4‑、PF6‑，式（Ⅰ））作催化剂，水为反应介质，反应温度为60~120°C，反应时间30~300min，碳水化合物可以有效转化生成5‑羟甲基糠醛。该催化体系具有反应条件温和，原料廉价易得，操作简单，催化剂易分离回收，且具有优良的重复使用性。
摘要（英）：

The invention relates to a heterogeneous catalytic system of effectively converting a carbohydrate into 5-hydroxymethylfurfural under a water nearing mild condition. By taking the carbohydrate as a raw material, an ionic liquid functional biomass charcoal sulfoacid shown in a formula (I) (BC-SO3H-IL-X, wherein X is equal to CF3SO<3->, BF<4-> and PF<6->) as a catalyst and water as a reaction medium, the carbohydrate can be effectively converted into 5-hydroxymethylfurfural, wherein the reaction temperature is 60-120 DEG C and the reaction time is 30-300 minutes. The catalytic system has the advantages that the reaction condition is mild, the raw material is low in price and is easily available, the system is simple to operate, the catalyst is easy to separate and recover, and the system has excellent reusability.
