ABSTRACT:
The invention is directed to a method of synthesizing silicoaluminophosphate molecular sieves using synthesis templates that contain at least one dimethylamino moiety, selected from one or more of N,N-dimethylethanolamine, N,N-dimethylpropanolamine, N,N-dimethylbutanolamine, N,N-dimethylheptanolamine, N,N-dimethylhexanolamine, N,N-dimethylethylenediamine, N,N-dimethylbutylenediamine, N,N-dimethylheptylenediamine, N,N-dimethylhexylenediamine 1-dimethylamino-2-propanol, N,N-dimethylethylamine, N,N-dimethylpropylamine, N,N-dimethylpentylamine, N,N-dimethylhexylamine and N,N-dimethylheptylamine. The use of dimethylamino moiety containing templates results in good quality SAPO molecular sieves of CHA framework type.
