HYDRATION OF CYCLOHEXENE CATALYZED BY ZEOLITES

Liquid phase hydration of cyclohexene over faujasite, mordenite and ZS M-5 catalysts at 10 MPa and temperatures 150 - 210 degrees C in a batc h system was studied. Influence of the type and Si/Al ratio of the zeo lite on the conversion of cyclohexene and the selectivity to cyclohexa nol formation was determined. Performance of the catalyst was also inv estigated through adsorption measurements of water and cyclohexene. Mo rdenite with the Si/Al ratio 70 provided the best results. The selecti vity to cyclohexanol was 99% at the conversion of cyclohexene 27% at 2 00 degrees C after 4 h. All the catalysts were regenerated by calcinat ion at 450 degrees C.
