| 摘 要： | 利用福建省沙县钾长石精粉水热晶化法合成13X分子筛,研究水碱比、碱硅比和晶化时间对合成13X分子筛的影响,采用X射线粉末衍射、扫描电子显微镜和热分析仪等对其性能进行探究。结果表明,最佳合成条件为：n(H2O)∶n(M2O)=40,n(M2O)∶n(SiO2)=1.4,晶化时间7 h。制备的13X分子筛与工业品13X分子筛技术指标相当,吸水率达到中国化工行业标准HG/T2690-95。

| Abstract: | Using potassium feldspar powder as the feedstock,13X molecular sieve was prepared by hydrothermal reaction.The influence of molar ratio of water to alkali,molar ratio of alkali to silica and crystallization time on the performance of 13X molecular sieve was investigated by X-ray powder diffraction,scanning electron microscopy,thermogravimetric and differential scanning calorimetry analysis.The results showed that the optimal synthesis condition was as follows：n（H2O）∶n（M2O） =40,n（M2O）∶ n（SiO2） =1.4,crystallization time 7 h.The related properties of self-made product corresponded with those of commercial 13X molecular sieve,and its water absorption rate met the state standards of chemical industry of China HG/T2690-95. |
