摘　　要：以去氢枞胺为结构导向剂、蒎烯为溶剂,通过微波辅助溶剂热法合成了磷酸铝,采用X射线衍射、氮气吸附-脱附、扫描电镜、透射电镜、热重和程序升温红外等方法对样品进行了表征。结果表明:去氢枞胺存在于磷酸铝原粉中起到了结构导向作用,反应温度与反应时间对样品的物相和孔结构有较大的影响,在170℃下反应4 h后,得到了孔结构优良的“绵状”无定形磷酸铝,比表面积272 m2/g,具有多级孔结构,平均孔径3.01 nm,孔容0.69 cm3/g。Aluminum phosphate was synthesized through microwave-assisted solvothermal method with dehydroabietylamine as the structure directing agent and pinene as the solvent.The products were characterized by X-ray diffraction,nitrogen adsorption-desorption,scanning electron microscope,transmission electron microscope,thermal gravimetric analysis and temperature-programmed infrared.The results indicated that the reaction temperature and duration showed significant effect on the phase and porosity of the aluminum phosphate,and the product with good porosity was obtained under the conditions of temperature 170℃and duration 4 h or more.The typical sample possessed“sticky”morphology with amorphous structure,and micro-and meso-porous with the BET specific surface area of 272.00 m2/g,average pore size of 3.01 nm and huge pore volume of 0.69 cm3/g.The results also confirmed the existence of dehydroabietylamine in the as-synthesized aluminum phosphate,which confirmed the structure-directing property of the dehydroabietylamine.
