中文摘要：

在溴化1-丁基-3-甲基咪唑离子液体中,于低温80°C反应30min即可制得结晶完好的磷酸铝方英石.详细考察了有机胺和HF的加入量、反应原料磷铝比和反应时间等对合成固体磷酸盐骨架结构的影响.粉末X射线衍射和高分辨固体核磁共振结果表明,合成的方英石晶体为α晶相,磷铝物种大部分位于分子筛骨架上,并以四配位的形式通过Al-O-P键相连.

英文摘要：

AlPO-cristobalite was prepared at low temperature of 80 °C for 30 min in the [bmim]Br ionic liquid.The effects of reaction conditions,such as the amount of organic amine and HF acid,the P/Al ratio,and reaction time,were investigated in detail in the ionothermal synthesis.Powder X-ray diffraction and high-resolution solid-state NMR show that the resultant sample is α-AlPO-cristobalite,and most of the Al and P species are located on the framework and connected by Al-O-P tetrahedron.
