Abstract
This invention relates to a process for preparing carboxylic acids by oxidizing an aldehyde with a peracid in the presence of an amine and/or amine N-oxide catalyst selected from the group consisting of a substituted or unsubstituted alkyl amine, alkyl amine N-oxide, aromatic amine, aromatic amine N-oxide, heterocyclic amine, heterocyclic amine N-oxide and mixtures thereof, to produce the carboxylic acid. Such carboxylic acids have utility for example as chemical intermediates.
