Abstract
An improved process for the production of unsaturated carboxylic acids and unsaturated nitrites from their corresponding Cto Calkanes, or mixtures of Cto Calkanes and alkenes, that involves 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.
