Abstract

Na, TPA-ZSM-5 with Si / Al mole ratio of about 130 was synthesized at low temperature and atmospheric pressure. These intermediate products were characterized by using XRD, XRF, FT-IR, NMR, and SEM. As a result, intermediate product were different from those that synthesized by autoclave method but spectroscopic characteristics of the final products showed to be in the typical ZSM-5 region. The defect sites were observed in the final product and removed by calcination at <TEX>$540^{\circ}C$</TEX>. Na, TPA-ZSM-5, aboveall, was synthesized at this condition within 48hr.
