Abstract：The CrAPO-5 and CrAPSO-5 were synthesized hydrothermally using triethylammonium as organic template, and the soluble silica and chromic nitrate were directly added in the process of synthesis. The reaction was studied, which used acetone as solvent and hydroperoxide as oxidant to produce cyclohexanone. When time is 12h, n(H_2O_2)/n(C_6H_(12)) is equal to 1.0 and the amount of catalysts is between 0.01g and 0.05g, the conversion ratio of cyclohexane can most come to 11.0% and the molar ratio of cyclohexnone ...

Key words：cyclohexane; cyclohexanone; catalytic oxidation; heteroatom; aluminophosphate molecular sieves
