摘　　要：以Raney铜催化糠醛加氢制备环戊酮和环戊醇。考察了溶剂类型、溶剂比例、溶剂与糠醛的比例、反应温度、氢气压力及反应时间等参数对糠醛转化率和选择性的影响。结果表明,以体积比4∶1的甲醇和水作为溶剂,糠醛与溶剂体积比1∶10,温度180℃,氢气压力3 MPa,反应时间4 h时,Raney铜催化糠醛加氢对于环戊酮和环戊醇表现出良好的活性和选择性,糠醛转化率达98.9%,环戊酮和环戊醇的选择性分别为52.9%和19.3%。采用XRD、BET和SEM对Raney铜催化剂的微观结构进行了表征。Raney copper has been employed for the catalytic hydrogenation of furfural（FA） to synthesize cyclopentanone（CPO） and cyclopentanol（CPL）.The effects of solvent type,volume ratio of solvent,volume ratio of reactants and solvent,reaction temperature,reaction pressure and reaction time on the FA conversion and selectivity are investigated in detail.Under the optimal conditions 〔V（methanol） ∶V（water） = 4∶1,V（FA） ∶V（solvent） = 1∶10,180 ℃,3 MPa and 4 h〕,the conversion of furfural is 98.9% and the selectivity of cyclopentanone and cyclopentanol are 52.9% and 19.3%respectively.The microstructure of Raney copper is characterized by means of XRD,BET and SEM.
