The invention relates to a process for the oxidation of meta-phenoxytoluene by selenium dioxide in the presence of a dehydrating agent to produce meta-phenoxybenzaldehyde containing less than 250 ppm dissolved selenium. The invention relates to a process whereby the benzaldehyde can be recovered from the reaction mixture as the bisulfite addition product at the rate of 90%/hr. The invention further relates to a stoichiometric selenium dioxide oxidation of meta-phenoxytoluene to yield a selectivity of about 90% or greater based on the toluene.
