Abstract
Catalyst for the prepn. of dicarboxylic anhydrides, esp. maleic anhydride, by the oxidn. of hydrocarbons contains (I) phosphorus, (II) vanadium, (III) oxygen, and (IV) beryllium, magnesium, calcium, strontium, or barium, the atomic ratio I/II being 1/2-2/1 (1-1.2/1) esp. 1.1/1, and of IV/II being at least 0.01/1. High yields of dicarboxylic anhydride. Reduced formation of by-prods. such as CO/CO2 as formation of 'hot spots' is practically eliminated.
