Abstract
An improved process for the production of unsaturated carboxylic acids and unsaturated nitriles from their corresponding Cto Calkanes, or mixtures of Cto Calkanes and alkenes, that involves oxidation in the presence of a supported Mo—V-based mixed metal oxide catalyst in a multi-stage reaction system which employs both separation of the oxidation product from one or more intermediate effluent streams, as well as feeding additional oxygen to reaction zones subsequent to the first reaction zone.
