Abstract
A novel synthetic crystalline borongermanosilicate molecular sieve material, designated boron SSZ-117x, is provided. The boron SSZ-117x can be synthesized using N,N,N,3,5-pentamethyladamantan-1-ammonium cations as a structure directing agent. The synthesis employs a boron pathway to achieve the boron molecular sieve. The boron SSZ-117x may be used in organic compound conversion reactions, such as reforming, and/or sorptive processes.
