【摘要】 选用了不同类型的表面活性剂作为模板剂合成磷酸铝介孔分子筛,实验结果表明,脂肪胺模板剂的浓度不会影响分子筛介孔相构型,介孔分子筛的孔径随烷基胺的链长增加而增大,其比表面积均达到了200m2/g以上.类型相同的表面活性剂作模板剂时,分子筛的孔径和比表面积并不随其浓度增加而增加.所合成的磷酸铝分子筛TG和°DTA曲线表明,磷酸铝分子筛在850℃以前具有一定的热稳定性.更多还原

【Abstract】 Differente types of the surfactant are selected as template synthesized mesostructured aluminophosphate.The test result shows that aliphatic amine concentration of template does not l not affect the mesostructured phase configuration,and the pore diameter of molecular sieve increases with the growth of clain lengt and both specific areas reach more than 200 m2/g.When the same type of surfactant is used as the template,the pore diameter of molecular sieve and specific area do not increase along with its concentration rise.The TG and DTA of synthetic mesostructured aluminophosphate shows that there is heat stabilization under 850℃.更多还原
