SYNTHESE VON CHA-TYP MOLEKULARSIEBEN |
摘要 |
<p>The invention is directed to a method for preparing microporous aluminophosphate or silicoaluminophosphate molecular sieves having the CHA framework type, the process comprising the steps of a) forming a reaction mixture comprising a source of aluminum, a source of phosphorus, optionally a source of silicon, at least one source of fluoride ions and at least one template containing one or more N,N-dimethylamino moieties, b) inducing crystallization of aluminophosphate and/or silicoaluminophosphate molecular sieve from the reaction mixture; c) recovering aluminophosphate and/or silicoaluminophosphate molecular sieve from the reaction mixture. The invention also relates to the molecular sieves obtained by this method and to molecular sieve catalyst compositions containing these molecular sieves.</p> |
