A process for the catalysed oxidation of ketones to esters or lactones with hydrogen peroxide in the presence of a carboxylic acid or anhydride solvent is provided. The process employs gamma alumina as a heterogeneous catalyst. In certain preferred embodiments, the catalyst also contains a tungsten-containing heteropolyacid. Preferably, the heteropolyacid contains phosphorus. In a related process, the catalyst accelerates the formation of percarboxylic acid solutions.
