Molecular sieve SSZ-117x, its synthesis and use
A novel synthetic crystalline aluminogermanosilicate molecular sieve material, designated SSZ-117x, is provided. SSZ-117x can be synthesized using N,N,N,3,5-pentamethyladamantan-1-ammonium cations as a structure directing agent. SSZ-117x may be used in organic compound conversion reactions and/or sorptive processes.
