红辉沸石合成A型分子筛的红外光谱研究
Synthesis of Molecular Sieve A from Stellerite and Characterization by IR Spectra
【摘要】 以天然红辉沸石合成了 A型分子筛 ,通过 XRD、IR光谱研究了其晶化过程。发现在 10 0 0— 95 0 cm-1、75 0— 60 0 cm-1、5 60 cm-1、4 60 cm-1处的红外吸收峰随结晶度有规律的变化 ,初步探讨其反应机理
【Abstract】 Molecular sieve A was prepared from natural stellerite.The synthetic process and the crystallization mechanism were investigated by XRD and IR spectra.The results showed that the vibration bands at 1000-950cm -1,750-600cm -1,560cm -1and 460cm -1 varied regularly during crystallization.
