Abstract:
1. A method for oxidizing a primary or secondary alcohol, the method comprising: a) preparing a catalyst composition having an initial concentration of each of a nitroxyl radical-comprising compound, a NO source, and a carboxylic or mineral acid or an anhydride of a carboxylic or mineral acid; b) adding at least one primary or secondary alcohol and a gas comprising oxygen and optionally also one or more solvents to the catalyst composition to obtain a reaction mixture; c) incubating the reaction mixture at a temperature between 0 and 100° C. or at a boiling point of the solvent, to obtain an oxidation reaction product of the primary or secondary alcohol in the reaction mixture; d) crystallizing the oxidation reaction product in the reaction mixture; e) removing the crystallized reaction product from the reaction mixture; and f) recovering the catalyst composition by adding the nitroxyl radical-comprising compound, the NO source, and the carboxylic or mineral acid or an anhydride of a carboxylic or mineral acid to the initial concentration; g) repeating operations b) through f) with the recovered catalyst composition.
