Activity enhancement of mesoporous silica (FSM-16) by modification with iron (II) sulphate for the isomerization of 1-butene

Dapaah JKA, Uemichi Y, Ayame A, Matsuhashi H, Sugioka M

The catalytic activity of mesoporous silica (FSM-16) for the isomerization of 1-butene was remarkably enhanced by modification with iron (II) sulphate. The enhancement of the activity of FSM-16 was attributed to the transformation of the silanol groups on FSM-16 into Bronsted acid sites by the inductive effect of FeSO4 and/or sulphate species formed by the decomposition of FeSO4.
