中文摘要:
      芳香腈是用途广泛的精细化学品,可用于合成农药、医药、塑料、染料、涂料等。本文总结了近二十年来芳香腈的主要制备方法,其中甲基芳烃氨氧化法可一步合成芳香腈,是工业上制备芳香腈最为经济、简便的方法,而氨氧化法生产芳香腈的关键是开发与底物相适应的催化剂;随后从催化剂载体、活性组分和助剂等方面对甲基芳烃氨氧化催化剂做了介绍,指出催化剂结构与性能之间存在密切关系;并简要评述了氨氧化反应条件和氨氧化反应器对催化性能的影响;最后指出高效催化剂的开发和氨氧化反应理论研究是今后的重点发展方向。
英文摘要:
      Aromatic nitriles are fine chemicals widely used in synthesis of pesticides, pharmaceuticals, plastics, dyes, paints and so on. In this paper, the main preparation methods of aromatic nitriles in recent twenty years are summarized. Among them, aromatic nitriles can be synthesized by ammoxidation of methylaromatics in one step, which is the most economical and convenient industrial process for aromatic nitriles. The key for such process is to develop a catalyst with active components compatible with the substrate. Subsequently, the catalysts for ammoxidation of methyl aromatics were introduced from the aspects of catalyst support, active components and promoters, and it was further pointed out that there was a close relationship between the structures and catalytic performances of the catalysts. The effects of ammoxidation reaction conditions and ammoxidation reactors on catalytic performances were briefly reviewed. Finally, the key directions would be focused on the development of high-efficiency catalysts and the theoretical study of ammoxidation reaction in the future.
