摘要:

以部分脱铝的Beta分子筛为母体, 采用同晶置换法将Sn植入骨架制备双功能[Sn,Al]-Beta分子筛, 并应用于葡萄糖一步催化生成5-羟甲基糠醛(5-HMF)反应中. 样品中Sn与Al的含量通过酸洗的浓度和酸洗的时间以及SnCl4处理的时间来控制. 由于骨架中有与Al相关为B酸位, 和Sn相关的L酸位, [Sn,Al]-Beta可作为一种双功能的固体酸催化剂. 优化了[Sn,Al]-Beta催化葡萄糖一步催化生成5-HMF的反应参数, 在最优Sn/Al比条件下, 葡萄糖转化率为60.0%, 5-HMF选择性为62.1%.

Abstract:

The one-pot synthesis of 5-hydroxymethylfurfural (5-HMF) from glucose was investigated, using [Sn,Al]-Beta catalysts prepared by a combination of partial dealumination and isomorphous substitution of Sn into the zeolite framework. The amount of Al in [Sn,Al]-Beta was adjusted by changing the concentration and acid treatment time, and the Sn content was varied by changing the SnCl4 vapor treatment time. [Sn,Al]-Beta contains framework Al-related Brönsted acid sites and tetrahedral Sn-related Lewis acid sites, and is therefore a bifunctional solid acid catalyst. The reaction parameters for the [Sn,Al]-Beta-catalyzed one-pot conversion of glucose to 5-HMF were optimized. [Sn,Al]-Beta with a suitable Sn/Al molar ratio gave a glucose conversion of 60.0% and 5-HMF selectivity of 62.1%.
