1) The least acidic aluminas give only cyclohexene.

2) Abstract Preparation of cyclohexene by dehydration of cyclohexanol on the catalyst ofp - Tolenesulfonic acid was studied.

3) Cyclohexene was synthesised by dehydration of cyclohexanol using phosphotungstic acid supported on active carbon as catalyst.

4) The allylic oxidation of cyclohexene was the dominate reaction,(http:///cyclohexene.html) and cyclohexene-2-one was obtained as the major product.

5) Using cyclohexene, benzene and styrene as probe molecules, hydrogenate reaction in situ of hydrocarbons adsorbed on noble metal catalysts (egg-shell distribution) were researched by in situ FT-IR.

6) Cyclohexene was synthesized by dehydration of cyclohexanol with anhydrous aluminum chloride as catalyst.

7) The solvent system includes a lower alkanol such as methanol or ethanol and cyclohexene.

8) The photocycloaddition between 8 - methoxypsoralin ( 8 - MOP ) and cyclohexene has been studied previously.

9) The terpolymerization of propylene oxide ( PO ) and cyclohexene oxide ( CHO ) with carbon dioxide ( CO 2 ) was investigated.

10) The deoxidization effect with hydrogen was superior to that with cyclohexene.

11) The HDS, HDN and HDY activities of the catalysts were tested with model compounds consisted of thiophene, dibenzothiophene, pyridine, quinoline, cyclohexene, hexamethylene.
