| Resumo: | In this work, the synthesis of zeolites using 1-butyl-3-methylimidazolium chloride [C4MI]Cl as a
structure-directing agent was investigated. The organic cation shows effectiveness and selectivity for
the syntheses of TON zeolites under different reaction conditions compared to the traditional structuredirecting agent, 1,8-diaminooctane. The 1-butyl-3-methylimidazolium cation lead to highly crystalline
materials and its role as OSDA in our synthesis conditions has been confirmed by characterization
techniques. ICP-OES confirms the presence of Al in the samples and 27Al MAS NMR analysis indicated
that aluminum atoms were incorporated in tetrahedral coordination. Scanning electron microscopy
indicated that changing the crystallization condition (static or stirring), zeolites with different crystal
size were obtained, which consequently affects the textural properties of the zeolites. Moreover, varying
some synthesis parameters MFI zeolite can also be obtained |
