Rare earth exchange of faujasites

Zeolites, 1985
Abstract When sodium zeolites X and Y with a wide range of silica to alumina ratios were ion-exchanged with rare earth ions by a standardized procedure, the degree of exchange was found to depend strongly on the SiO 2 Al 2 O 3 ratio.

Polar arenes in faujasites

1994
Summary Adsorption sites of m-dinitrobenzene and m-nitroaniline in zeolites CaY, NaY and NaX have been determined by means of X-ray powder diffraction. The structures have been solved applying Rietveld refinement in combination with difference Fourier synthesis.

Thermal behavior of synthetic faujasite

Journal of Catalysis, 1969
Abstract Data are presented to show that the thermal stability of synthetic faujasite is dependent on the level of sodium present. A simple relationship has been found between the sodium content of ammonium-exchanged faujasite and the temperature at which breakdown of the zeolite structure occurs.

Random siting of aluminum in faujasite

The Journal of Physical Chemistry, 1982
Recent high resolution solid state /sup 29/Si NMR experiments have led to the determination of the relative concentrations of five chemically nonequivalent tetrahedral silica atoms in zeolites. Tetrahedrally coordinated silica may bond to zero, one, two, three, or four O-A1 groups in the zeolite framework leading to, in each case, a different chemical ...
