PREPARATION METHOD OF OXIDATION CATALYST |
| 摘要 |
<p>A method for preparing an oxidation catalyst comprises (a) mixing a deactivated phosphorous-molybdenum-alkali metal catalyst with a liq. compsn. consisting of water, ammonium ion and nitrate ion, (b) removing the liq. compsn. by drying, and (c) calcining the obtd. dried catalyst. The oxidn. catalyst is used in the production of unsatd. carboxylic acids by the vapour-phase catalytic oxidn. of unsadt. aldehydes.</p> |
