| 英文摘要 | methanol conversion over sapo molecular sieve dnl-6 was investigated from the view point of the reaction mechanism. the organic materials confined in the cavities of dnl-6 were mostly polymethylbenezenes. by combination of in situ nmr study with ex situ gc-ms measurements, the structure of heptamethylbenzenium ion (heptamb(+)) formed during mto reaction was definitely confirmed. further evidences from the mass spectra and c-13 solid-state nmr spectra in the isotopic switch experiments showed that the side chain methylation mechanism was the main reaction route for olefin formation from hydrocarbon pool species.
