摘要: The present invention relates to an integrated process for producing unsaturated carboxylic acids from the corresponding C2-C4 alkane. begins with performance of thermally dehydrogenation reactions which convert a alkane its alkene, and involve exothermically converting portion alkene by oxidative in exothermic reaction zone, presence oxygen suitable catalyst, then feeding products zone endothermic wherein at least remaining unconverted is endothermically dehydrogenated form additional quantity same carbon dioxide other catalyst. are provided catalytic vapor phase partial oxidation conversion acid or nitrile. Unreacted recovered product stream recycled back reactions.
