Patent ID: 7939043

Claim:
A method of synthesizing a silicoaluminophosphate or aluminophosphate molecular sieve comprising a CHA framework-type material, the method comprising: (a) providing a synthesis mixture comprising a source of aluminum, a source of phosphorus, optionally a source of silicon, and at least one organic template of formula (I): [R 1 R 2 R 3 R 4 N] + X − (I) wherein each of R 1 , R 2 , R 3 , and R 4 is independently an acyclic alkyl group having at least one carbon atom, the total number of carbon atoms in said alkyl groups R 1 , R 2 , R 3 , and R 4 is greater than 8 but less than 16, and X − is an anion; and (b) inducing crystallization of said synthesis mixture to form said molecular sieve.
