揭示一种制备钒/磷混合氧化物催化剂前体的方法，该方法包括在磷源存在下使钒源在有机介质中反应。有机介质包括(a)异丁醇或异丁醇和苄醇的混合物，(b)多元醇。(a)和(b)的重量比值为99∶1至5∶95。活化后，钒/磷混合氧化物催化剂前体是非芳族烃如正丁烷转变为马来酐的优良催化剂。 Active vanadium/phosphorus mixed oxide catalyst for the conversion of non-aromatic hydrocarbons, e.g., n-butane, into maleic anhydride. The catalyst is prepared...
