MOLECULAR SIEVE SSZ-90, ITS SYNTHESIS AND USE

摘要

A new crystalline zinc (silico)aluminophosphate molecular sieve designated SSZ-90 is disclosed. SSZ-90 is isostructural with the DFO framework type and is synthesized using an ionic liquid as both the solvent and the structure directing agent. The ionic liquid [Q+A−] comprises a cation (Q+) selected from the group consisting of 1,3-diisopropylimidazolium, 1,3-diisobutylimidazolium, and 1-isopropyl-3-isobutylimidazolium and an anion (A−) which is not detrimental to the formation of the molecular sieve.
