摘　　要：苯甲醛是一种重要的有机合成中间体和精细化工产品,广泛应用于医药、农药、化妆品、香料以及食品等行业。以价格低廉的苯甲酸或苯甲酸甲酯为原料,催化加氢一步制取无氯苯甲醛,符合原子经济和绿色生产的要求,操作简单,且得到的产品纯度高、不含氯,已经吸引了国内外研究学者的广泛关注。笔者总结国内外以苯甲酸或苯甲酸甲酯为反应底物,通过气相加氢选择性生成苯甲醛的反应机理、催化剂组分、反应条件及产品产率等方面的研究进展。基于该反应具有高温、低压的特点,提出催化剂的选用原则和设计思路:催化剂应具有弱酸及强碱性位点、合适的氧空穴浓度以及良好的耐热稳定性。并对该工艺的未来发展做出展望。Benzaldehyde is an important fine chemical product and organic synthesis intermediate.It has been widely used in the production of medicine,pesticide,cosmetics,food and other industries.Catalytical hydrogenation of benzoic acid and methyl benzoate to benzaldehyde follows the requirements of atomic economy and green chemistry.This process has some advantages,e.g.,simple,no chlorine in the product,and high selectivity.Based on recent literatures,this paper summarizes the research progress on reaction mechanism,catalyst composition,reaction conditions and product yield of this process.Based on the reaction characteristics of high temperature and low pressure,catalyst design strategy is proposed,i.e.,weak acid and strong alkaline sites,appropriate oxygen vacancy concentration and good heat-resistant stability.Direction of future studies in this area is also suggested.
