FT-IR Spectroscopic Study of 1,3-Diaminopropane Adsorbed on Type A, X and Y Zeolites
نویسندگان
چکیده
Zeolites are the best known microporous molecular sieves and adsorbe molecules below a particular size in their pore structures. Therefore they are considered as heterogenous catalysts and sorbents [1]. The catalytic properties of zeolites can be understood by investigating the adsorption characteristics of reactions on their surfaces [2, 3]. During the past years the adsorption of some compounds which include amine groups have been studied by using infared spectroscopy [4]. Very recently, the adsorption of 1,3-diaminopropane which contains primary aliphatic amine groups on calix[4]arene has been studied by using FT-IR (Fourier Transform Infrared) [5]. The purpose of the present work is to offer the IR spectra of 1,3-diaminopropaneadsorbed on NaA, CaA, NaX and NaY zeolites in which the more small cavities relative to calix[4]arenes are formed.

Enhancement of CO2/CH4 Adsorptive Selectivity by Functionalized Nano Zeolite
In this work, we have modified a synthesized Y-type zeolite (Si/Al = 2.5), with three different amines to investigate of the influence of adsorbent’s surface modification on CO2 selectivity over CH4. The pristine and amine-functionalized NaY zeolites were characterized by X-ray diffraction (XRD), thermal gravimetric analysis (TGA), Fourier transform infrared (FT-IR), and N2 adsorption. The resu...

Zeolites A, X and HS were synthesized from natural Iranian Kaolinite by alkaline fusion,,followed by refluxing the mixture. The transformation of zeolites X to HS and Y to P were studied at different time intervals by X-ray diffraction and Scanning Electron Microscopy (SEM). It was revealed that in solution, zeolites HS and P are more stable than zeolites X and Y respectively
