Abstract
Abstract A new composition comprising crystalline antimonophosphoaluminate, designated MCM-14, and the novel method for its synthesis are 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.
