| 摘 要：以三乙胺為模板劑在合成過(guò)程中直接加入了硝酸鉻及硅溶膠,水熱合成了CrAPO 5和CrAPSO 5雜原子磷鋁分子篩。以丙酮為溶劑,過(guò)氧化氫為氧化劑,考察了環(huán)己烷氧化制取環(huán)己酮的反應。在反應時(shí)間12h、原料配比為n(H2O2)/n(C6H12)=1.0、催化劑通量為0 01～0 05g條件下,環(huán)己烷的轉化率最高可達到11 0%,酮醇比可達到1 39。 |

| 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 ... |
