Patent ID: 7670589

Claim:
A method of synthesizing a crystalline material comprising a CHA framework-type molecular sieve, the method comprising: a) forming a reaction mixture capable of forming said crystalline material, wherein the reaction mixture comprises a structure directing agent having the formula: [R 1 R 2 R 3 N—R 4 ] + Q − wherein R 1 and R 2 are joined to form a substituted or unsubstituted five-membered nitrogen-containing heterocyclic ring, R 3 is an alkyl group having 2 to 4 carbon atoms and R 4 is selected from a 4- to 8-membered cycloalkyl group, optionally, substituted by 1 to 3 alkyl groups each having from 1 to 3 carbon atoms; and a 4- to 8-membered heterocyclic group having from 1 to 3 heteroatoms, said heterocyclic group being, optionally, substituted by 1 to 3 alkyl groups each having from 1 to 3 carbon atoms and the or each heteroatom in said heterocyclic group being selected from the group consisting of O, N, and S, or R 3 and R 4 are hydrocarbyl groups having from 1 to 3 carbon atoms joined to form a nitrogen-containing heterocyclic structure; and Q − is a anion; and b) recovering from said reaction mixture said crystalline material comprising a CHA framework-type molecular sieve.
