CRYSTALLINE ALUMINOPHOSPHATES AND RELATED COMPOUNDS

T 5244 NOVEL CRYSTALLINE ALUMINOPHOSPHATES AND RELATED COMPOUNDS Crystalline aluminophosphates and related compounds having in the as-synthesized anhydrous form the chemical composition: mR(XnAlqPx)O2, wherein R is derived from a 2,2'-bipyridyl moiety, X represents one or more elements which can be substituted for Al and/or P, wherein m = 0.01 - 0.33 n = 0 - 0.40 q = 0.30 - 0.60 x = 0.30 - 0.60 and wherein n + q + x = 1. The compounds can be prepared from a forming solution or gel comprising a source of aluminium, a source of phosphorus, optionally a source of at least one component X, and a template source based on a 2,2'-bipyridyl moiety, 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.
