Abstract
The present invention relates to a process of oxidation of alcohols selectively to aldehydes or ketones with molecular oxygen using a TEMPO based catalyst, Fe-bipyridyl or Fe-phenantroline co-catalyst and N-bromosuccinimide promoter in acetic acid solvent. The oxidation takes places at high rates and high aldehyde selectivity at temperatures in the range 45-50° C. and oxygen or air pressures of 0-15 psi. The alcohol conversion of 95-100% and aldehyde selectivity higher than 95% are achieved over 3-4 hours reaction time. Aldehydes such as 3,3-dimethyl-1-butanal can be produced efficiently using the present invention.
