Interaction between Peroxy Radicals and Acetaldehyde on Solid Surfaces and Its Role in the Oxidation of Aldehydes

Resumo

Heterogeneous interaction between peroxy radicals and acetaldehyde in a capillary reactor treated with boric acid was studied. The possibility of a reaction occurring between adsorbed peroxy radicals and acetaldehyde was confirmed. Based on a comparison of these data and those obtained for other surfaces along with the ignition and slow oxidation of aldehydes in reactors with identical surfaces, it was concluded that the oxidation of aldehydes includes not only a homogeneous component but a heterogeneous component as well.
