摘　　要：以福建省沙县天然钾长石矿为原料,采用水热合成法制备了13X沸石分子筛,利用X射线粉末衍射(XRD),傅里叶变换红外光谱(FT-IR),差热分析(DTG-TG)以及静态水吸附法等手段对影响分子筛的合成工艺和产物性能等因素展开详细研究.实验结果表明,m(钾长石)∶m(无水碳酸钠)=1.4,800℃焙烧时,钾长石矿的分解最充分;其中钠硅比、水碱比是影响分子筛合成的重要工艺参数;所合成产物的吸附量达到国家化学工业产品标准.13X molecular sieve was synthesized from potassium feldspar in Shaxian, Fujian province by hydrothermal synthesis. Analysis on factors that affect optimal process parameters and performances was conducted by XRD,FT-IR,DTG-TG and static adsorption. The results indicated that potassium feldspar was fully decomposed when molar ratios of potassium feldspar powerd and soda at 1.4, temperature at 800 ℃. The factors which influenced the quality of the molecular sieve mainly included the molar ratios of Na2 O/ SiP2 and H2O/Na2 O. The adsorb ability of products reached the State Standards of Chemical Industry in China.
