Synthesis crystalline molecular sieves

In a process for synthesizing a crystalline molecular sieve, an aqueous synthesis mixture is produced capable of forming the crystalline molecular sieve. Crystallization of the synthesis mixture is induced so as to form crystals of said molecular sieve in the synthesis mixture and, when crystallization is complete, the molecular sieve crystals are allowed or caused to separate from the remainder of the synthesis mixture to produce a solid phase comprising said molecular sieve crystals and a supernatant liquid phase. The supernatant liquid phase is then decanted from the solid phase to recover the molecular sieve crystals and the crystals are dried without initially being subjected to washing or filtration.
