Abstract
A method for synthesizing a crystalline silicophosphoaluminate is provided. The composition has ion-exchange properties and is readily convertible to catalytically active material. The synthesis method requires an organic phase, and an aqueous phase. The silicon, phosphorus and aluminum components of the silicophosphoaluminate may, optionally, be replaced with other elements in the plus 4, 5 and 3 valence states, respectively.
