    摘要: A method is disclosed of synthesizing a crystalline material comprising a CHA framework type molecular sieve and having a composition involving the molar relationship: (n)X2O3:YO2, wherein X is a trivalent element; Y is a tetravalent element; and n is from 0 to less than 0.01. The method comprises preparing a reaction mixture capable of forming said material, said mixture comprising a source of water, a source of an oxide of a tetravalent element Y and optionally a source of an oxide of a trivalent element X, wherein the reaction mixture is substantially free of fluoride ions added as HF; maintaining the reaction mixture under conditions sufficient to form crystals of the crystalline material; and than recovering the crystalline material. The reaction mixture comprises either a specific directing agent for directing the formation of a CHA framework type molecular sieve and/or a H2O:YO2 molar ratio of greater than 20. In one embodiment, the resultant crystalline material is free of stacking faults and/or any intergrown phase with an AEI framework type molecular sieve.

    摘要: In a method of synthesizing an aluminophosphate or metalloaluminophosphate molecular sieve, a synthesis mixture is provided comprising water, a source of aluminum, a source of phosphorus, optionally a source of a metal other than aluminum, a tertiary amine, and an alkylating agent capable of reacting with said tertiary amine to form a quaternary ammonium compound capable of directing the synthesis of said molecular sieve. The synthesis mixture is maintained under conditions sufficient to cause the alkylating agent to react with the tertiary amine to produce the quaternary ammonium compound and to induce crystallization of the molecular sieve.
