摘要： 固体超酸由于其优良的催化性能,近年来倍受重视[1,2]。其中以全氟骨架的磺酸树脂Nafion H应用最广。POSA(全氟辛基磺酸,C8F17SO3H)也是一种化学性质稳定、易回收的固体超酸,具有与Nafion H相似的氟碳链磺酸结构。

关键词: 醇, 脱水反应, 烯烃, 超酸, 全氟辛基磺酸

Abstract: Various tipe of alkenes can be simply prepared in high yield from primary, secondaryand tertiary alcohols, using solid superacid POSA(C8F17SO3H, perfluorooctanesulfonicacid)as a catalyst. The catalyst can be reused many times without any loss of its activity.

Key words: alcohol, dehydration, alkene, superacid, perfluorooctanesulfonic acid
