| Abstract | SAPO-5 molecular sieve with AFI topology has been ionothermally synthesized by microwave irradiation and using eutectic mixture based on pentaerythritol and choline chloride as reaction medium. The resultant SAPO-5 molecular sieve was characterized by X-ray diffraction (XRD), 29Si magic-angle spinning nuclear magnetic resonance (29Si MAS-NMR), N2 physisorption, scanning electron microscopy (SEM), energy disperse spectroscopy (EDS), and thermogravimetry–differential thermal analysis (TG–DTA). 29Si MAS-NMR showed that the incorporation of Si in the calcined sample was mainly by the SM3 mechanism. N2 physisorption measurements confirmed that the resulting SAPO-5 molecular sieve contained mesopores with a pore radius of about 3–30 nm. CHN and TG–DTA analysis revealed that it was choline that directed the synthesis of SAPO-5. Moreover, the factors affecting the crystallization of SAPO-5 molecular sieve were investigated in detail. The results showed that P2O5/Al2O3 ratios, HF/Al2O3 ratios and reaction temperature had great impact on the crystallization of SAPO-5. |
