摘要
在Ｎａ２Ｏ－（ＣＴＭＡ）２Ｏ－ＳｉＯ２－Ｈ２Ｏ与（ＴＭＡ）２Ｏ－（ＣＴＭＡ）２Ｏ－ＳｉＯ２－Ｈ２Ｏ体系中分别合成了不同硅铝比及全硅ＭＣＭ－４１分子筛作品，考察了诸因素对晶比过程的影响，同时对其酸性、热稳定性和催化性能进行了表征．
The aluminosilicates with different Si/Al ratios and pure silicates with MCM-41 molecularsieve structure have been synthesized in two kinds of systems: Na2O-(CTMA)2 O-SiO2-H2O and(TMA)2O-(CTMA)2O-SiO2 h -H2 O,respectively.The effect of various factors on the crystallization process and the crystallization kinetics of the samples are studied.The acidity, thermal stability and catalytic reactivity are also characterized.
