OXIDATION VON ALDEHYDEN ZU CARBONSÄUREN

摘要

This invention relates to a process for preparing carboxylic acids by oxidising an aldehyde with molecular oxygen or a gas containing molecular oxygen in the presence of an amine and/or amine N-oxide promoter 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.
