The values ofHammett function for the H-Y faujasite at different temperatures have been determined on the basis of UV-Vis diffuse reflectance spectra of the five indicators recorded at 25–230 graduate C. It has been found that the acidity of H-Yachieves the superacid values of H0 < –12 at T greater-than 170 graduate C.
