Abstract:

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.

Key words: dehydroabietylamine, solvothermal, aluminum phosphate
