摘要:
Furfural is produced by mixing an aqueous feedstock solution containing C5 sugar and/or C6 sugar with a heated high boiling, water-miscible solvent, such as sulfolane, and a solid acid catalyst. Furfural product and water can be distilled off, leaving non-volatile solvent behind. Furfural yields of over 70% at as high as 99% conversion have been obtained with this process with sulfolane as the reaction solvent and zeolite beta as the solid acid catalyst. Also, certain by-products (e.g., humins) solubilized in the reaction solvent can be precipitated by addition of water or aqueous feedstock solution and then removed by filtration, thereby providing a convenient and effective way of removing these undesirable byproducts from the reaction mixture.
摘要(中):
通过将含有C5糖和/或C6糖的水性原料溶液与加热的高沸点,水混溶性溶剂如环丁砜和固体酸催化剂混合来制备糠醛。 糠醛产品和水可以蒸馏出来,留下非挥发性溶剂。 用环丁砜作为反应溶剂和沸石β作为固体酸催化剂,该方法已经获得高达99%转化率的糠醛产率超过70%。 此外,溶解在反应溶剂中的某些副产物(例如,胡氏体)可以通过加入水或原料溶液沉淀,然后通过过滤除去,从而提供从反应混合物中除去这些不期望的副产物的方便有效的方法。
