ABSTRACT:
One or more aldehydes or ketones, or both, are produced by pyrolyzing an alcohol having at least two carbon atoms or an aldehyde having at least two carbon atoms, or both, over a Group VIII metal oxide catalyst, preferably a catalyst composed predominantly of iron oxide, notably ferric oxide. Preferably, the catalyst additionally contains a minor proportion of a Group IV-A metal oxide, most preferably germanium dioxide. The process provides a good yield of lower molecular weight aldehydes, such as formaldehyde, or higher molecular weight ketones, such as acetone, 2-pentanone and the like. Selective manufacture of products enriched either in aldehyde or in ketone can be achieved by a simple adjustment in the reaction conditions employed.
