Abstract
Silicophosphoaluminates are crystallized from a two-phase reaction mixture comprising sources of silicon oxide, aluminum oxide and phosphorus oxide and a suitable directing agent. The silicophosphoaluminates produced have ion exchange properties and are readily convertible to catalytically active material.
