| Abstract: | Nanosized rare earth solid superacid SO42/TiO2-Nd2O3 was prepared and was used as a catalyst for cyclohexand dehydration to form cyclohexene.The influence of various preparation parameters such as the concentration of Nd3 ,the concentration of H2SO4 and the calcination temperature on the catalytic activity was studied.It indicates that SO42-/TiO2-Nd2O3 has fairly high catalytic activity on the dehydration of cyclohexand and the yield of cyclohexene can reach 79.73%.The SO42-/TiO2-Nd2O3 catalytic mechanism for cyclohexand dehydration and the Nd3 effect on the catalytic activity was also disccused. |
