摘    要:以异丙醇铝为铝源,正磷酸为磷源,三乙胺作模板剂,采用水热反应合成了AlPO4-5分子筛。应用不同浓度氢溴酸对AlPO4-5分子筛进行化学剪裁,制备AlPO4-5-AlBr3催化剂。FESEM、XRD、N2吸附-脱附等表征结果表明,合成的AlPO4-5是规整的微孔六方棱柱,化学剪裁制备的担载型催化剂AlPO4-5-AlBr3依然保持规整的六方棱柱。催化氧化实验表明,质量分数30%双氧水作为氧化剂,在乙酸乙酯溶剂中,催化剂AlPO4-5-AlBr3对部分环酮具有较好的催化活性。

关 键 词:水热合成  化学剪裁  Baeyer-Villiger反应  催化技术

Abstract:AlPO4-5 molecular sieves were prepared by hydrothermal reaction using triethylamine as template,aluminum isopropoxide and orthophosphate as the source of aluminum and phosphorus.Via chemical tailoring method with different concentrations of hydrobromic acid,AlPO4-5-AlBr3 catalysts were obtained.Several techniques,such as high-resolution field-emission scanning electron microscopy(FESEM),X-ray diffraction(XRD) and N2 adsorption,were employed to investigate their morphology,structure as well as component.The characterization shows that AlPO4-5 was hexagonal crystal with microporous structure,after chemical tailoring,AlPO4-5-AlBr3 still maintained the structure.The catalytic test was performed using 30% H2O2(mass fraction) as oxidant and ethyl acetate as solvent.It is revealed that the catalyst had good performance for some ketons,and could be reused several times.
Keywords:hydrothermal synthesis  chemical tailoring  Baeyer-Villiger reaction  catalytic technology
