Abstract
In a method of synthesizing a silicoaluminophosphate or aluminophosphate molecular sieve comprising a CHA framework-type material, a synthesis mixture is provided comprising a source of aluminum, a source of phosphorus, optionally a source of silicon and at least one organic template of formula (I):[RRRRN]X  (I)wherein each of R, R, R, and Ris independently an acyclic alkyl group having at least one carbon atom, the total number of carbon atoms in said alkyl groups R, R, R, and Ris greater than 8 but less than 16, and Xis an anion. The synthesis mixture can then be crystallized to produce the desired molecular sieve.
