Zusammenfassung:	In a method of synthesizing a silicoaluminophosphate molecular sieve, a synthesis mixture is prepared by combining a source of phosphorus and at least one organic directing agent; and then cooling the combination of the phosphorus source and organic directing agent to a temperature of less than or equal to 50 DEG C., prior to introducing a source of aluminum into the combination. After addition of a source of silicon, the synthesis mixture is heated to a crystallization temperature of between about 100 DEG C. and about 300 DEG C. and the molecular sieve is recovered.
