摘要：

The synthesis of pure phase ZSM-11 (MEL) at temperatures below 100 degrees C has been achieved using extremely dense gels with minimal water contents. Both hydroxide and fluoride routes were investigated using N,N-diethyl-3,5-dimethylpiperidinium and 2,2-diethoxyethyltrimethylammonium based templates. Highly crystalline materials were successfully synthesised within relatively short reaction times using a wide range of reaction conditions. The syntheses are shown to be not as efficient as the related ZSM-5 (MFI) materials, suggesting that the structure directing power of the template molecules is critical for low temperature reactions.
