摘要: Cyclohexanol is dehydrated to cyclohexene by heating it in the presence of a heteropolyacid catalyst. The heteropolyacid is selected from tungstophosphoric acid, tungstosilicic acid, molybdophosphoric acid and molybdosilicic acid. Tungstophosphoric acid can be improved in its catalytic performance by calcination. The dehydration reaction is preferably carried out in liquid phase continuously removing cyclohexene by distillation.
