Crystalline silicophosphoaluminate from a two phase medium

摘要

An improved method of synthesis for a composition comprising crystalline silicophosphoaluminate (MCM-2) is provided. The composition has ion-exchange properties and is readily convertible to catalytically active material. The synthesis method requires two liquid phases comprising a suitable organic or inorganic directing agent and specific reactants, including a specific aluminum phosphate of the ALPO-5 structure.
