1,4-萘醌是重要的精细化工原料,主要用于医药、农药和染料的合成,其合成方法主要是液相氧化法和气相氧化法,分别介绍了两种方法的研究进展及各自特点,其中液相氧化法工业化时间较长应用广泛;相对于液相氧化法,气相氧化法则是较新的合成方法,并有较多优点,寻求一种更适合的催化剂将是气相氧化法今后研究的重点。还介绍了两种实验室合成法,即微波和超声波催化合成法,并对两种方法中影响萘醌收率的因素进行了阐述。
1,4-Naphthoquinone is an important fine chemical raw material, mainly used in the synthesis of medicine, pesticides and dyes. The synthesis methods are mainly liquid phase oxidation and gas phase oxidation. The progress of the two methods and their respective characteristics , Of which liquid phase oxidation process for a long time widely used; relative to the liquid phase oxidation, gas phase oxidation is a relatively new synthesis method, and has many advantages, to find a more suitable catalyst will be the future research of the gas phase oxidation the key of. Also introduced two laboratory synthesis, that microwave and ultrasonic catalytic synthesis method, and the two methods affect naphthoquinone yield factors are described.
