Abstract :
Catalytic behavior of perchloric acid when supported to mesoporous silica SBA-15 (SBA-15/HClO4) was investigated as a
heterogeneous Bronsted acid. Its reactivity and leaching possibility were studied in cascade ring opening-cyclocondensation
sequence of diketene and alcohol with aldehyde in the presence of either of urea or ammonium acetate. Results showed that
this catalyst can be highly recyclable for several cycles.
