以草鱼鱼骨为载体,采用水热法制备了草鱼鱼骨(GCB)负载金属卤化物催化剂(MX_2/GCB)。采用FT-IR、XRD、ICP-OES、比表面积及孔径分析仪等手段对载体和催化剂进行了表征,并将制备的催化剂用于苯甲醚与乙酸酐的酰化反应,考察了反应条件对酰化反应的影响以及催化剂的重复稳定性能。结果表明,在催化苯甲醚与乙酸酐的酰化反应中,ZnBr_2负载量为1 mmol/g的ZnBr_2/GCB的催化活性最高,在反应时间6 h、催化剂用量2.0 g的条件下,乙酸酐的转化率可达85.4%,对甲氧基苯乙酮的选择性为97.2%,催化剂重复使用5次后仍具有较高的活性。

The grass carp bone (GCB) supported metal halides catalysts (MX2/GCB) were prepared by hydrothermal method and characterized by FT-IR, XRD, ICP-OES and specific surface area analysis. The effects of reaction conditions and stability of MX2/GCB in the Friedel-Crafts acylation of anisole and acetic anhydride were studied. The results indicated that the highest conversion 85.4% of acetic anhydride with p-methoxy acetophenone selectivity of 97.2% was obtained with ZnBr2/GCB containing 1 mmol/g ZnBr2, under the reaction time of 6 h and the ZnBr2/GCB amount of 2.0 g. Furthermore, the ZnBr2/GCB catal...
