摘　　要：利用共沉淀法合成了不同Cu/Al比例的铜铝水滑石类化合物,且利用XRD,IR对此类化合物进行了表征.首次用于催化苯酚羟化反应,并获得了较好的结果,同时探讨了Cu/Al比例,反应温度,反应介质及介质的pH值对反应活性的影响.初步提出了反应机理.Copper - Aluminium Hydrotalcite - like compounds are synthesized by coprecipitation and characterized with XRD and IR. Catalysis of the above mentioned HTLcs are investigated in the phenol hydroxylation,good results are obtained. Meanwhile, the effects of the ratio of Cu/Al, reaction temperature, reaction medium and pH of reaction system are discussed. The reaction mechanism is also proposed.
