KF/Al₂O₃ reached maximum activity at the pretreatment temperature(T_p) of 623K or 723K in 1-butene isomerization at 273K, according to the amount of KF loaded.Further increment of T_p lowered the activity of KF/Al₂O₃ due to the suppression of[Al-OH^-F]strong basic sites through dehydroxylation.Changes in the state and function of F^- caused the deactivation of KF/Al₂O₃ at high T_p.
