摘要: 应用核磁共振和拉曼光谱研究了L沸石导向剂的陈化机制。实验结果表明,当铝源与硅源混合后铝酸根离子与硅酸根离子之间聚合反应很快,同时高聚态硅酸根离子发生了解聚。L沸石导向剂陈化反应的控制步骤是低聚态硅铝酸根离子之间或低聚态硅铝酸根离子与低聚态硅酸根离子之间的定向聚合反应。

Abstract: The ageing mechanism for the directing agent of zeolite Lwas studied by means of NMRand Laser-Raman spectroscopyThe experimental results show that after mixing the sources of alumina and silica the polymerization between aluminate and silicate anions is very rapid and at the same time the silicate anions of high degree of condensation are depolymerizedThe controlling step of the ageing reaction for the directing agent of zeolite Lis directional polymerization between aluminosilicate oligomers or between aluminosilicate and silicate oligomers.
