An Aluminophosphate with sequence number Six Teen (AST) type framework silico alumino phosphate (SAPO-16) molecular sieve is successfully synthesized through an eco-friendly, economic and a faster crystallization method by microwave treatment. In the present investigation, SAPO-16 is synthesized in a non-aqueous medium using hexamethyleneimine as a template. The structural and morphological properties are characterized by PXRD, SEM-EDX, TEM, BET, FT-IR, NH₃-TPD, and MAS-NMR techniques. Powder X-ray diffraction studies show that the synthesized samples are highly crystalline. EDX results showed that the calcined sample contains 0.7 Al₂O₃: 0.8 P₂O₅: 0.4 SiO₂ on the surface. TEM analysis inferred that the sample contains 50-100 nm sized particles with uniformed triangle morphology. The TGA analysis reveals that the sample loses about 20% of it's weight from room temperature to 550 °C. BET-adsorption isotherm shows that the surface area is 270 m²/g. Structural integrity is shown by FT-IR analysis and Magic angle spinning Nuclear magnetic resonance spectroscopic analysis. ²⁹Si MAS NMR analysis infers that most of the Si is present in tetrahedral Si:2Al:2Si environment. TPD-NH₃ reveals that the presence of maximum amount of strong Brønsted acidity with minor amount of moderate bronsted acidity. The catalytic activity on Benzaldehyde acetalization reaction shows that the reactants have a maximum of 80% conversion in 8 h with maximum turn over a number of 14.5 × 10⁻² and turn over the frequency of 4.0 × 10⁻⁵.

通过生态友好，经济，快速的结晶方法，通过微波处理成功地合成了序列号为六个青少年（AST）型骨架硅铝磷酸盐（SAPO-16）的铝磷酸盐。在本研究中，SAPO-16是在非水介质中以六亚甲基亚胺为模板合成的。通过PXRD，SEM-EDX，TEM，BET，FT-IR，NH ₃ -TPD和MAS-NMR技术表征结构和形态特性。粉末X射线衍射研究表明，合成的样品是高度结晶的。EDX结果表明，煅烧后的样品中含有0.7 Al ₂ O ₃：0.8 P ₂ O ₅：0.4 SiO _2。在表面上。TEM分析推断该样品包含50-100 nm大小的颗粒，具有均匀的三角形形态。TGA分析表明，从室温到550°C，样品的重量减少了约20％。BET吸附等温线表明表面积为270m ² / g。FT-IR分析和魔角旋转核磁共振光谱分析显示了结构的完整性。²⁹ Si MAS NMR分析表明，大多数Si存在于四面体Si：2Al：2Si环境中。TPD-NH ₃表明存在最大量的强布朗斯台德酸度和少量的中等布朗斯台德酸度。苯甲醛缩醛化反应的催化活性表明，反应物在8 h内具有最高80％的转化率，最大转化数为14.5×10 ^-2，翻转频率为4.0×10 ^-5。
