Efficient co-templating roles of amines and amides admixed with alkylammonium salts for the stabilisation of new AlPO4-n topologies. In Zeolites and Mesoporous Materials at the dawn of the 21st century. Proceedings of the 13 International Zeolite Conference, 194-194, ISBN: 9780444502384. Amsterdam, Elsevier, 2001.9780444502384AUT: JLO01215;http://hdl.handle.net/10400.1/1257Two different aluminophosphate structures were synthesised in aqueous media using as main template methylamine (MA), directly added, or generated in situ from methylformamide (MF). Both involve novel AlPO4-n topologies that undergo structural transformations upon template removal, yielding above 350°C microporous thermostable materials with interesting properties. Tetraalkylammonium (TEA) cations were used optionally as co-templates along with MA. Only non protonated MA was found incorporated into the pore volume of both structures, in relatively strong interaction with the framework oxygens. TEA appeared to stabilise one of the phases at defined stages of nucleation and/or growth processes, without playing any specific structure-directing role.engSynthesisMethylamineconference object2012-06-14
