Abstract:
The oxidation of isobutyraldehyde produces isobutyric acid and byproducts, such as isopropyl formate. A method of reducing the isopropyl formate byproduct in the oxidation of isobutyraldehyde is described. The method uses a co-solvent, such as acetone, to the isobutyraldehyde feed to increase both the selectivity of the reaction to isobutyric acid and the production rate of isobutyric acid so that the isopropyl formate byproduct is significantly reduced.
