ZSM-5 zeolites were synthesized from aqueous solutions in Na2O-TPA2O-Al2O3-SiO2-H2O system, and there was an optimum condition in the relations between TPA2O content of initial gel and the amount of crystals formed. The zeolite crystals were comparatively uniform in size and their SiO2/Al2O3 ratios (R values) of framework were in the range from 80 to 6400.
The adsorbed amount of n-hexane on the Na-form was in close agreement with that of silicalite. In the conversion of methanol to hydrocarbons, the H-form containing only about 0.6 Al atoms per unit cell gave a high yield of aliphatics and aromatics.
