摘　　要：以功能化酸性离子液体[HSO3-ppy][CF3COOH]作催化剂,由芳香醛与乙酸酐反应,在室温、无溶剂条件下,以83%～97%的产率制备了1,1-二乙酸酯。该方法操作简单方便,产率较高,对环境友好,催化剂易回收循环使用,产物结构经1 HNMR,IR确证。A series of 1,1-diacetates were synthesized by the acetalization reactions of aromatic aldehydes with acetic anhydride catalyzed by [HSO3-ppy][CF3 COOH] under solvent-free con- dition. The reactions were carried out at room temperature with yields between 83% and 97%. The results indicated that the proposed method is easy, high yield and environmental friendly. The functionalized ionic liquid catalyst could be recycled and reused. All the products have been identified by 1HNMR and IR spectra.
