Abstract
The invention is directed to a method of synthesizing aluminophosphate or silicoaluminophosphate molecular sieves and in particular to the synthesis of silicoaluminophosphate molecular sieves using synthesis templates in combination with a source of fluoride comprising at least two fluoride substituents. The use of such fluorine containing compounds results in good quality low silica SAPO molecular sieves of CHA framework type.
