| Research Abstract |
The pore-size dependence of the acidic properties of mesoporous silica FSM-16 in the range from 1. 8 to 3. 8 nm was investigated with the catalysis of 2-butanol dehydration and using FTIR spectra of adsorbed pyridine. The activity was the highest for FSM-16 with a minimum pore diameter, and decreased with increasing poresize. Basic nanospace was synthesized by the homogeneous modification of FSM-16 with 3-(triethoxysilyl) pyridine, which is a rigid substrate without an alkyl cha in as linker. Aldol condensation of butanal gave the corresponding dimer in high yields over 3-(triethoxysilyl) pyridine-modified FSM-16. Nitogen-substituted FSM-16 was synthesized by the NH3 treatment at high temperatures. Knoevenagel reaction takes place over nitrogen-substituted FSM-16.
