BORON SSZ-41, ITS SYNTHESIS AND USE
20250345780 · 2025-11-13 · ·

A novel synthetic crystalline molecular sieve material, designated boron SSZ-41 is provided. The boron SSZ-41 is a boronzincosilicate molecular sieve having the framework structure of SSZ-41. It can be synthesized using 1,1-(1,4-butanediyl)bis[4-aza-1-azoniabicyclo[2.2.2]octane] dications as a structure directing agent. The boronzincosilicate SSZ-41 may be used in organic compound conversion reactions and/or sorptive processes.
