T 5340 A B S T R A C T CRYSTALLINE ALUMINOPHOSPHATES AND RELATED COMPOUNDS Crystalline aluminophosphates and related compounds having in the as-synthesised dried form the chemical composition expressed as a R (b P205) (c A1203) (d SiO2) (e MeO) (z H2O) wherein R represents a diamine of the general formula R2R3N-R1-NR4R5 wherein R1 represents a C8-C14 carbon chain which may contain one or more inert substituents and each of R2, R3, R4 and R5 represents a hydrogen atom or an alkyl group which may contain one or more inert substituents and Me represents a divalent metal moiety, wherein: a:b = 0.5 - 1 (c + e):b = 0.4 - 0.95 d:b = 0 - 0.25 (c + e):a = 0.8 - 1.2 and z:b at least 0.1. The compounds can be prepared from a forming solution or gel comprising a source of aluminium. a source of phosphorus, a source of a diamine as defined hereinabove and optionally a source of at least one metal moiety MeO, wherein the appropriate forming components are initially present in specific molar ratios and which mixture is kept at elevated temperature for a period of time sufficient to produce a crystalline aluminophosphate or related compound, followed by separating off the crystalline product obtained and drying, and which may subsequently be calcined.
