METHOD FOR OLEFIN EPOXIDATION WITH SIMULTANEOUS PRODUCTION OF NYLON PRECURSOR Russian patent published in 2009 - IPC C07D301/19 C07C55/14 C07D201/06

Abstract RU 2359964 C2

FIELD: chemistry.

SUBSTANCE: invention is related to combined method, which combines olefin epoxidation with preparation of cyclohexanone and cyclohexanol, which are intermediate for production of adipic acid or caprolactam - nylon precursors. Usually cyclohexanone and cyclohexanol are produced by oxidation of cyclohexane with production of cyclohexylhydroperoxide, which is then removed or decomposed. However, in this invention intermediate compound, cyclohexylhydroperoxide is used as oxidant for olefin epoxidation with valuable product making in this process. In process of epoxidation catalyst is used, which contains transition metal and amorphous porous inorganic oxide, which has disorderly interconnected mesopores. The specified mesopores account for at least around 97 volume percents from total volume of mesopores and micropores. Specified porous inorganic oxide has specific area surface from 400 to 1100 m²/g.

EFFECT: porous inorganic oxide is characterised by X-ray picture, having peak from 0,5 to 3,0 degrees 2θ.
