PHOSPHORUS/VANADIUM CATALYST PREPARATION

A process for preparing a catalyst for maleic anhydride production wherein a +5 vanadium compound such as V 2 O 5 , an anhydrous phosphoric acid, and optionally promoters are admixed in an organic alcohol solvent, the admixture is rapidly brought to reflux and thereafter refluxed to reduced the vana...

Zusammenfassung:A process for preparing a catalyst for maleic anhydride production wherein a +5 vanadium compound such as V 2 O 5 , an anhydrous phosphoric acid, and optionally promoters are admixed in an organic alcohol solvent, the admixture is rapidly brought to reflux and thereafter refluxed to reduced the vanadium compound to the desired degree, the reflux mixture is cooled, precursor crystals are separated by filtration and then dried and calcined.
