| Abstract: | Some catalytic systems for the synthesis of glutaraldehyde by one step catalytic oxidation of cyclopentene and hydrogen peroxide in a non water solvent were studied. The function of cocatalyst B 2O 3 and its optimum concentration were investigated. A excellent catalytic system WO 3 B 2O 3 was determined. Based on the experimental data, the kinetic equation was derived by poly parameter nonlinear optimization(Powell Program). Under the recommended conditions, the conversion of cyclopentene is 67%. The yield and the selectivity to glutaraldehyde are 63% and 91% respectively. |
