Patent

CA 2589467

A method is disclosed for synthesizing high-silica molecular sieves having the CHA crystal structure using a structure directing agent comprising a cation derived from 1-adamantamine, 3-quinuclidinol or 2-exo-aminonorbornane. The synthesis is conducted in the absence of fluorine.

L'invention concerne un procédé de synthèse de tamis moléculaires à haute teneur en silice présentant une structure cristalline CHA au moyen d'un agent d'orientation de structure qui comprend un cation dérivé de 1-adamantamine, de 3-quinuclidinol ou de 2-exo-aminonorbornane. La synthèse est effectuée sans fluor.
