Abstract

Abstract: Amphiphilic HZSM-5 zeolite particles were prepared by the chemical vapor deposition of (CH3)3SiCl on the external surface of HZSM-5 zeolite followed by post-evacuation at 423–523 K to remove excessive hydrophobic CH3 groups. With a similar internal surface property and pore size to the parent zeolite, they exhibited obviously superior catalytic performance in the hydrolysis of isoamyl acetate.

Key words: trimethylchlorosilane, HZSM-5, amphiphilic zeolite, chemical vapor deposition, phase-boundary catalysis
