Abstract
When Y zeolites are impregnated with ethanolic acetylacetone, the 29Si and 27Al magic-angle spinning n.m.r. spectra can be used to determine the correct Si/Al framework ratios and to quantify the amount of extra-framework aluminiums; evidence suggests that this impregnation does not cause further dealumination of the zeolitic material.Keywords
