Реферат: A number of experiments on the synthesis of SAPO-11 crystals in different media (water; equimolar H2O/EtOH; low H2O/EtOH), using two methods of precursor mixing and various temperature regimes of hydrothermal treatment (HT) has been performed. It has turned out that one-stage HT at 200 °C had not provided SAPO-11 crystallization in low H2O/EtOH medium, only non-porous aluminum phosphates had been obtained, while a two-stage HT at 200 and 120 °C on the first and second stages, respectively, had allowed us to synthesize the AEL phase. Whereas equimolar water–ethanol synthesis medium has resulted in a mixture of both microporous and non-porous phases. The last one is apparently the result of the unusual properties of water–ethanol crystallization system. SAPO-11 samples which were obtained in different media have possessed “screw-like”, “tubular-like”, and “spindle-like” morphologies. SAPO-11 synthesized in the medium with the predominance of ethanol has had significant changes in physicochemical properties compared with ones obtained in water.
