Catalyst for prepn of phthalic anhydride by oxidn of ortho-xylene - contg large amt. of vanadium pent:oxide on amorphous aluminosilicate as micro-carrier

In a catalyst for the prepn of phthalic anhydride from o-xylene and atmos O2, an amorphous aluminosilicate is used as micro-carrier for V2O5 as active component. ADVANTAGE - The amt of V2O5 in the catalyst is 70-05% (claimed), giving a cheaper catalyst with high activity and selectivity, similar to...
