摘要
在无溶剂,聚苯乙烯负载酸性离子液体(P[Vim-PS][HSO_4])为催化剂的条件下,利用苯酚和丁醇酮在酸性条件下进行Friedel-Crafts反应合成覆盆子酮。催化剂通过FT-IR、TG-DTG元素分析进行表征。与传统的合成方法相比,利用聚苯乙烯负载酸性离子液体为催化剂避免使用大量的有机溶剂,反应条件温和,反应时间短,产率高,易分离,且催化剂可循环利用,催化活性基本保持不变。
Under solvent-free condition,the polystyrene supported acidic ionic liquid（ P[Vim-PS][HSO4]） is used as catalyst to synthesize raspberry ketone from phenol and butanolone via Friedel-Crafts reaction. The catalyst is investigated by FT-IR,TG-DTG and elemental analysis. Compared with the traditional synthetic methods,the employment of polystyrene supported acidic ionic liquid as catalyst could avoid the use of a large amount of organic solvents. This method has the advantages of mild conditions,short reaction time,high product yield and easy separation. The catalyst can be recycled and catalytic activity remains unchanged.
