| 摘要 |
<p>This invention relates to catalysts useful in the vapour phase oxidation of hydrocarbons, such as 1,3-butadiene to furan and maleic anhydride. The catalysts comprise vanadium oxides, vanadium phosphorus oxides or vanadium antimony oxides incorporated in a matrix comprising oxides or oxyhydroxides of silicon, titanium, tantalum and/or niobium derived using sol-gel chemistry, optionally inthe presence of an organic directing agent, such as dodecylamine.</p> |
