| Abstract: | Preparation of cyclohexene by dehydration of cyclohexanol over catalyst ZrO_2-SO_4~(2-) is studied. The influences of catalyst amount, reaction temperature and reaction time on dehydration are tested. The optimal reaction conditions were as follows: when mass fraction of the catalyst to cyclohexanol was 10%, after carrying the reaction for 1 h at 170～180 ℃, a yield of 87.4% can be realized. |
