ABSTRACT:
Crystalline aluminophosphate compositions having pore windows formed by 18 tetrahedral members are prepared from a forming mixture containing sources of aluminum, phosphorus and optionally, silicon. The forming mixture further contains a directing agent comprising a mixture of quaternary nitrogen compound and amine in a molar ratio of 0.01 to 0.025. The resulting product exhibits greater stability than compositions made from amine directing agent.
