Patent ID: 6914030

Claim:
A process for preparing a crystalline silicoaluminophosphate molecular sieve of CHA framework type, the process comprising: (a) forming a reaction mixture comprising a source of aluminum, a source of phosphorus, a source of silicon and at least one organic template which comprises one or more N,N-dimethylamino moieties 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; and (b) inducing crystallization of crystalline molecular sieve of CHA framework type.
