Rb-X bonds

After sorption of toluene on Rb-X, the bands attributed to the asymmetric and symmetric CHj-stretching vibrations were observed at 12 and 20 cm lower wavenumbers than after sorption of toluene on HZSM5. This is interpreted as a weakening of the C-H bonds due to strong interactions of the methyl group with the lattice oxygens of Rb-X. [Pg.452]

In situ IR studies of sorbed toluene and methanol under non reactive conditions showed that both reactants assume different adsorption structures on HZSM5 and Rb-X. While methanol is stabilized as hydrogen bonded methoxonium ion in the pores of HZSM5, it is coordinatively bound via its oxygen to the cations in zeolite Rb-X. In addition to this coordinative bond, strong lateral interactions of the hydroxyl group of methanol with the basic oxygens of the lattice of zeolite Rb-X were detected. [Pg.454]
