| Abstract: | SO 2- 4/TiO 2-Al 2O 3 solid superacid were prepared by incorporation of appropriate amounts of Al 2O 3 into SO 2- 4/TiO 2,and used in the reaction of intramolecular dehydration of cyclohexanol. Experimental results show that SO 2- 4/TiO - 2Al 2O 3 has good catalytic ability. Amounts of Al 2O 3 and catalyst used and reaction time on the yield of cyclohexene were investigated. The catalyst could be easily separated from the products and regenerated.They are no pollution to the environment. |
