摘要:         吡啶与1,4-丁基磺内酯反应首先制备具有磺酸基团的两性盐,然后再与对甲苯磺酸反应合成吡啶-磺酸功能化离子液体,通过核磁共振(NMR)和红外光谱(IR)表征其结构。该离子液体作为催化剂及溶剂,催化2-萘甲醚的乙酰基化反应,设计正交试验L9(34)优化其反应件。结果表明,2-萘甲醚的物质的量为5mmol、2-萘甲醚/乙酸酐的物质的量比为1∶5,离子液体质量0.3g,120℃下反应6.0h,2-萘甲醚的转化率达90.7%。主产物2-甲氧基-1-萘乙酮的选择性为99.4%;其中,影响反应物转化率和产物选择性的主要因素为反应时间和温度。

Abstract:

    Pyridine-sulfonic acid functionalized ionic liquid([PY-BS] [TsO]) is prepared by the reaction of p-toluenesulfonic acid with sulfonic groups amphoteric salt(PY-BS) that is prepared by the reaction of Pyridine with 1,4butyl sultone. Then, [PY-BS][TsO] ionic liquid can be characterized by IR, NMR. And it is chosen as the catalyst and solvent in the Friedel-Craft acylation of 2-methoxynaphthalene optimizing the reaction conditions by orthogonal experiment of L9(34). The orthogonal experiment result shows that the conversion of 2-methoxynaphthalene (2-MN) reaches 90.7% and the selectivity of 2-methoxy-1-acetyl naphthalene as the main products is 99.4% in the follwing conditions that the 2methoxynaphthalene is 5 mmol, the mol ratio of 2-methoxynaphthalene/acetic anhydride is 15, ionic liquid is 0.3 g and reaction time is 6.0 h at 120 . The main factors affecting the reaction rate and product selectivity are the reaction time and temperature.
