| Abstract: | In this paper, it is proved that a necessary condition for the green and semi-miniature synthesis of cyclohexene, that 732 types of strong acid polystyrene cation exchange resin was employed as catalyst. Using this method for synthesis of cyclohexene can avoid the environmental pollution caused by strong liquidacid with high yield and the catalyst can be used repeatedly. Moreover, in chemistry teaching, it would he increasing students＇ environmental awareness by the green chemistry experiments training |
