✦ Synopsis

Zeolite Y has been dealuminated

with ammonium hexafluorosilicate.

The influence of the reaction conditions -concentration of reactants, number of treatments, and time and temperature of reactionon the final properties of the products has been studied. The materials thus obtained have been characterized using X-ray diffraction and i.r. spectroscopy (OH stretching vibrations and pyridine adsorption).
