摘要: 本文提出两个经验方程来表示Na23-NMR谱强度同导向剂在不同温度下的陈化时间以及完全晶化所需时间的关系。在此基础上提出了在导向剂存在下NaY型沸石晶体生长的动力学模型,并说明了导向剂的作用机理。
Abstract: In this paper, two empirical equations, I = 6 (T +100) t100.0035T and I = 398.15(t2 - 0.8)-0.06lg11T, were suggested to express the correlation between the intensity ( I ) of Na23-NMR spectrum, which is proportional to the number of Na+ in crystal lattice of Xtype zeolite, aging time (t1) and the time (t2) of complete crystallization of "directing-agent" at different temperature. On the basis of these results, a kinetic model of crystal growth of NaY type zeolite in presence of so-called directing-agent was suggested, and the mechanism of the "directing-agent" effect has been characterized.
