以四乙基氢氧化铵为模板剂 ,正硅酸乙酯为硅源 ,静置水热法合成全硅 β沸石 .用硝酸 (13mol/L)对硅铝比(Si/Al)为 2 0的Na β沸石回流脱铝 .焙烧后的上述两样品经粉末X射线衍射、低温氮吸附、核磁共振、红外光谱、吸附等温线等表征 ,发现合成的全硅 β沸石骨架与孔道结构完美并具有很高的表面疏水 /亲有机物的吸附特性 . Using tetraethylammonium hydroxide as templating agent and tetraethylorthosilicate as silicon source, hydrothermal synthesis of all-silico zeolite beta was carried out.Using nitric acid (13mol / L) for Si / Al ratio of 20 Na zeolite was reflowed and dealuminated.The above two samples were characterized by powder X-ray diffraction, low temperature nitrogen adsorption, nuclear magnetic resonance, infrared spectroscopy, adsorption isotherm and so on, and found that the synthesized all-Si zeolite framework and pore structure were perfect and had Very high surface hydrophobic / organophilic adsorption properties.
