Solvothermal aluminophosphate zeotype synthesis with ionic liquid precursors?

Abstract

We have carried out a study of aluminophosphate framework synthesis using several amine based ionic liquids and their parent amines as solvent and template. The results suggest that in the presence of fluoride ions from hydrofluoric acid the ionic liquids and their parent amines produce the same frameworks, while in synthesis without fluoride ions the products are not related. The results include the synthesis and crystal structure of a novel extra-large pore material using 1-methylpyrrolidine as solvent and template. The relationship between this and sodalite, which can be synthesised in cobalt aluminophosphate form using an ionic liquid prepared from 1-methylpyrrolidine is described. The crystal structures of two other new layered materials are also presented.
