Abstract: Na-ZSM-5 (Si/Al= 50, 100 and 150) zeolites have been synthesized in alkaline pH of 10.5 ± 0.2 by hydrothermal process without the use of template and with tetraethyl orthosilicate as silicon source. The MFI phase formation is confirmed under various synthesis conditions. The synthesized material possesses strong acid sites and the Na-ZSM-5 catalyst ion exchanged to H-ZSM-5 has been can be used to investigate the dehydration of 4-Cl-benzaldoxime. The dehydration of benzaldoxime is confirmed by the observing nitrile stretch at 2400 cm-1. The conversion levels ( ̴ 51%) show that the synthesized catalyst possesses strong Bronsted acid sites.
