ABSTRACT:
An integrated process for producing cyclohexanone oxime, a caprolactam precursor, is provided wherein a secondary alcohol is utilized to generate the hydrogen peroxide oxidizing agent and as a reaction medium for ammoximation. The ketone produced as a co-product is recycled back to the secondary alcohol by hydrogenation.
