【Abstract】 CrAPO-5 and CrAPSO-5 were synthesized hydro thermally using triethylammonium as organic template,and the soluble silica and chromic mitrate 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 was 12h,n(H 2O 2)/n(C 6H 12) was equal to 1.0 and the amount of catalysts was between 0.01g and 0.05g,the conversion ratio of cyclohexane can most come to 11.0% and the molar ratio of cyclohexnone t cyclohexnol was 1.39 at best.更多还原
