Location of Chemisorbed Methylium Ions in Zeolites by Neutron Diffraction
Original language description
Distribution of chemisorbed methyl groups and sodium cations in the structure of NaY, NaX and NaLSX zeolites was estimated by neutron diffraction. Changes in the distribution of structural sodium cations in the lattice after chemisorption of methyl cations have been detected. Distancies of C-O in surface methoxy groups in empty cavities were found to be longer than in ordinary crystalline metalloorganic compounds with bridging methoxyls. The location of chemisorbed methyl groups at O1 lattice oxygen type was found to be most probable for NaY. Nuclear densities of chemisorbed methyl were detected in NaX at O1 and at O4 lattice oxygen. The origin of the split signal at 58 ppm on NaX and NaLSX samples has been discussed. Zeolitic catalysts are used in industrial chemistry.
