Process for preparing a vanadium phosphorus oxygen catalyst composition by an organic solution method

摘要

A process for preparing a vanadium, phosphorus oxygen containing catalyst composition capable of partially oxidizing hydrocarbons (e.g., n-butane) to form a carboxylic anhydride (e.g., maleic anhydride), and a process for using this catalyst to form such anhydrides is disclosed. The catalyst composition is prepared by an organic solution technique followed by activation in an air-hydrocarbon atmosphere.
