在无溶剂,聚苯乙烯负载酸性离子液体(P[Vim-PS][HSO4])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.
