Amphiphilic HZSM-5 zeolite particles were prepared by the chemical vapor deposition(CVD) of trimethylchlorosilane((CH3)3SiCl) followed by heating and evacuation.During CVD,(CH3)3SiCl reacted with terminal silanols on the external surface of HZSM-5 to generate hydrophobic groups.The resulting zeolite particles were hydrophobic.During heating of the zeolite particles to 423-523 K and evacuation,the(CH3)3Si groups decomposed by Si-C bond breaking,and one to two of the CH3 groups were removed off,which resulted in amphiphilic zeolite particles.This modification has little effect on the pore size and internal surface.In the phase-boundary catalytic hydrolysis of isoamyl acetate,these amphiphilic zeolite particles were located at the water-organic boundary and exhibited better catalytic activity than the parent zeolite.
