ABSTRACT:
Alkylpyrimidines are dealkylated to the corresponding pyrimidines by contacting with an oxidation catalyst containing one or more oxides of at least one of the elements of the group consisting of Bi, Mo and V in the presence of water and oxygen in the gas phase at a temperature of 300.degree.-450.degree. C.
