Abstract
An integrated process combines olefin epoxidation with production of cyclohexanone and cyclohexanol for nylon. Cyclohexanone and cyclohexanol normally produced by the oxidation of cyclohexane, in which cyclohexyl hydroperoxide is generated and is removed or decomposed down stream. However, this invention utilizes the intermediate of cyclohexyl hydroperoxide as an oxidant for the olefin epoxidation and meanwhile generates a valuable product.
