摘要: A new approach to the evaluation of accessibility acid sites in microporous/mesoporous materials is developed and tested using a series dealuminated mordenites. This based on an IR-spectroscopic study consecutive adsorption substituted alkylpyridines (pyridine, 2,4,6-trimethylpyridine, 2,4,6-triethylpyridine) carbon monoxide. method allowed us determine strength number with various degrees accessibility. The 2,4,6-triethylpyridine types studied. extinction coefficients are determined McBain balance placed cell for measurements.
