SYNTHESIS OF SILICOALUMINOPHOSPHATES

The invention is directed to a method of synthesising silicoaluminophosphate molecular sieves and in particular those of framework type CHA and AEL. The method uses synthesis templates that comprise one or more tertiary dialkylbutylamines, wherein the alkyl groups are not butyl. The use of such temp...

Beschreibung
Zusammenfassung:	The invention is directed to a method of synthesising silicoaluminophosphate molecular sieves and in particular those of framework type CHA and AEL. The method uses synthesis templates that comprise one or more tertiary dialkylbutylamines, wherein the alkyl groups are not butyl. The use of such templates. especially N,N dimethylbutylamine, results in SAPO-11 of a desirable platelet morphology. L'invention concerne un procédé de synthèse de tamis moléculaires de silicoaluminophosphate, plus précisément ceux du type de structure CHA et AEL. Le procédé utilise des gabarits de synthèse comprenant un ou plusieurs dialkylbutylamines tertiaires, les groupes alkyle n'étant pas butyle. L'utilisation de ces gabarits, notamment N,N-diméthylbutylamine, donne lieu à SAPO-11 d'une morphologie de lamelle voulue.
