Intergrown molecular sieve, its synthesis and its use in the conversion of oxygenates to olefins

A molecular sieve comprises at least one intergrown phase of an AFX framework-type molecular sieve and a CHA framework-type molecular sieve and is conveniently synthesized using a combination of N,N,N′N′-tetramethylhexane-1,6-diamine and N,N-dimethylcyclohexylamine as organic directing agents.
