Synthesis of AlPO_4-31 from nonaqueous systems

摘要

The aluminophosphate molecular sieve AlPO_4-31 has been synthesized from a nonaqueous system in the presence of hexamethyleneimine as templating agent and has been characterized by means of X-ray powder diffraction (XRD), scanning electron microscopy (SEM), FT-IR, differential thermal analysis (DTA) and thermogravimetric analysis (TG) and ~(27)Al and ~(31)P MAS NMR techniques.
