摘　　要：以Fe(NO3)3·9H2O和(NH4)6Mo7O24·4H2O为原料,采用溶胶-凝胶法于不同条件下制备Fe2(MoO4)3超微粒子催化剂,并研究了这些催化剂对正丁醇选择性氧化制备正丁醛的催化性能,从而找出Fe2(MoO4)3超微粒子催化剂选择性氧化正丁醇的最佳实验条件。结果表明,制备Fe2(MoO4)3超微粒子的适宜条件为:溶液初始pH=1.0,以EDTA为螯合剂,EDTA/(铁+钼)摩尔比为0.4时制得的催化剂对正丁醇的选择性氧化性能最好,此时正丁醛的产率可达39.3%。With sol-gel method and different conditions, catalyst Fe2（MoO4）3 ultrafme particle was synthesized from ferric nitrate and ammonium molybdate, and in the hope of finding out the optimum experimental conditions of n-butanol＇s selective oxidation to butanal, these catalysts＇ catalytic capability was also studied. Results showed the optimum experimental conditions were as follows： pH of initial solution 1.0, EDTA as ligand, EDTA/（Fe＋Mo） （molar ratio） 0.4. Under above conditions, the yield of butanal reached up to 39.3%.
