| Abstract: | A new solid acid catalyst SO 2- 4 MoO 3 TiO 2 was prepared. FT IR indicated that the catalyst had strong surface acid centers. FT IR spectra of pyridine absorbed on the surface showed that the catalyst had Br o ¨nsted acid sites. The catalyst showed high catalytic activity in preparation of cyclohexene by dehydration of cyclohexanol. The optimum conditions were as follows: cyclohexanol 40 g, catalyst 4 g,reaction temperature 175°C and reaction time 1.0 h. The yield of cyclohexene was 90%. |
