Mesoporous MCM-type catalysts with amine were synthesized by co-condensation of tetraethyl orthosilicate (TEOS) and 3-aminopropyltriethoxysilane (APTES) using n-dodecylamine as template under neutral condition
and then characterized by XRD
N2 adsorption-desorption
IR and TGA.The results indicated that the incorporation of aminopropyl was successful
but the excess aminopropyl might destroy the mesoporous structure of the catalysts
which resulted in the decreases of specific surface area and pore volume.The influences of aminopropyl content and catalyst dosage on the cracking reaction were investigated.Under optimal condition
the yield of methylchloromonosilanes and conversion of high-boiling residues reached 63.3% and 76.6% respectively.
