ABSTRACT:
An integrated process for producing cyclohexanone oxime, a caprolactam precursor, is provided wherein isopropanol is utilized to generate the hydrogen peroxide oxidizing agent. The acetone produced as a co-product is recycled back to the secondary alcohol by hydrogenation. Ammoximation of cyclohexanone is performed in the presence of water and an alcohol other than isopropanol such as methanol or t-butyl alcohol.
