以十六烷基三甲基铵和十二烷基三甲基氯化铵为表面活性剂，1,3,5-三异丙苯为辅助有机添加剂，制备了六方介构烷基三甲基铵-磷酸铝材料。这些材料在600℃下煅烧得到热稳定的介孔磷酸铝材料，其表面积大于700m2 - 1，孔径在1.8 ~ 3.9nm之间。经31p - MAS NMR测定，煅烧前的六方介结构材料骨架凝聚较少，这使得材料在煅烧过程中发生一定的收缩，从而形成多孔结构。对水和苯的吸附数据表明，介孔磷酸铝材料具有相对亲水的介孔。
Hexagonal mesostructured alkyltrimethylammonium–aluminophosphate materials were prepared by using hexadecyltrimethylammonium and dococyltrimethylammonium chlorides as surfactants and by utilizing 1,3,5-triisopropylbenzene as an auxiliary organic additive. Calcination of these materials at 600°C yielded thermally stable mesoporous aluminophosphate materials with large surface areas above 700m2g−1and with pore diameters in the range from 1.8 to 3.9nm. The hexagonal mesostructured materials before calcination had less condensed frameworks as determined by31P MAS NMR, which caused certain shrinkages during calcination for the formation of the porous structures. Water and benzene adsorption data indicated that the mesoporous aluminophosphate materials had comparatively hydrophilic mesopores.
