摘要: 以2 - 甲氧基萘为反应底物, 以磷钨酸( H3PW1 2O4 0) 为催化剂, 以醋酐为酰化试剂, 研究2 - 甲氧基萘的
傅 - 克酰基化反应。考察了反应温度、 反应物的物质的量比、 反应时间和催化剂质量等因素对2 - 甲氧基萘转化率和主
要产物选择性的影响。实验结果表明, 2 - 甲氧基萘酰化反应的主产物是2 - 甲氧基 - 1 - 萘乙酮。适宜的反应条件为: 以
H3PW1 2O4 0为催化剂, 催化剂质量为0. 0 8g、 反应时间为3h、 温度8 0℃、 2 - 甲氧基萘与乙酸酐的物质的量比为1∶2。
在此条件下反应, 2 - 甲氧基萘的转化率为8 3. 3 2%, 2 - 甲氧基 - 1 - 萘乙酮的选择性达9 1. 3 9%。

Abstract: The catalytic properties of phosphotungstic acids for the Friede1Crafts acylation of 2methoxynaphthalene(MN) with aceticanhydride (AA) were investigated.The effect of various reaction conditions, such as reaction temperature, ratio of reactants, reaction time and catalyst dosage on conversion of 2methoxynaphthalene and the selectivity to main product were studied. The results show that 2methoxy1acetonaphthone was main priority products in the acylation reaction of 2methoxynaphthalene. The optimal reaction conditions were as follows: 0.08 g H3PW12O40 as catalyst, reaction time 3 h, reaction temperature 100 ℃, molar ratio of 2methoxynaphthalene to acetic anhydride 1∶2. Under these conditions, the conversion of 2methoxynaphthalene is 83.32%and the selectivity is up to 91.39% .

Key words: 2methoxynaphthalene, FriedelCrafts acylation, Phosphotungstic acids, Catalysis;Acetic anhydride
