CRYSTALLINE ALUMINOPHOSPHATES AND RELATED COMPOUNDS

T 5341 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 represents 1,4 - diaminobutane as defined hereinbefore, X represents one or more elements which can be substituted for Al and/or P, wherein m = 0 - 0.33 n = 0 - 0.40 q = 0.30 - 0.60 x = 0.30 - 0.60 and wherein n + q + x = 1 and having an X-ray diffraction pattern containing at least the lines as given in Table A, B, C, D, E or F. The compounds can be prepared from a forming solution or gel comprising a source of alumina, a source of phosphorus, 1,4-diaminobutane and optionally a source of at least one component X wherein the various sources are present in certain specified molar ratios, by keeping the solution or gel at elevated temperature for a time sufficient to produce crystalline aluminophosphates or related compounds.
