摘　　要：苯乙酮是用途极广的化工原料中间体,不仅可以制备多种化工产品,还被广泛应用于高分子合成材料工业、石油化工和精细化工等众多领域.本文在前期研究经验基础上,探索合成了功能型硒离子液体,并利用红外光谱、核磁共振氢谱、液质联用对其结构进行了表征.以硒离子液体兼做溶剂及催化剂,通过单因素实验,确定了乙苯氧化为苯乙酮的最佳反应条件,为工业生产提供了理论支持.Acetophenone is extremely versatile chemical intermediates, which can not only prepare a variety of chemical products, but also widely applied in polymer synthetic material industry, petrochemical and fine chemical industry. The oxidation of ethyl benzene has been investigated widely in these years, which has broad market prospects. Based on our previous research, selenium ionic liquid was synthesized, and characterized by infrared （IR）, nuclear magnetic resonance （1H-NMR）, and LC-MS. Then the selenium ionic liquid was used both as solvent and catalyst, in oxidation reaction of ethyl benzene to acetophenone. Determined by single factor experiment, the optimum reaction condition was confirmed, which provide the fundamental theory for its industry application.
