Abstract
Monocarboxylic acids or esters thereof are reduced to aldehydes using hydrogen and a vanadium catalyst. For example, meta-phenoxybenzoic acid can be effectively converted to meta-phenoxybenzaldehyde in a vapor phase process using hydrogen as the carrier gas/reductant and a catalyst composed at least initially of vanadium pentoxide, either supported or unsupported.
