- W2489342811 abstract "Transalkylation reactions are observed in Y zeolites partially exchanged with ethyl-, diethyl-, and triethylammonium cations (EA, DEA, and TEA, respectively) heated above 150°C in air or under vacuum, in the presence of residual water molecules. The main reactions may be depicted schematically as follows: (EA) Y → (DEA)Y > (NH4+)Y, (DEA)Y → (EA)Y > (TEA)Y, and (TEA)Y → (DEA)Y > (EA)Y, the main constituent in the gas phase being C2H4. They are similar to those observed in montmorillonite in the presence of a water vapor pressure of a few torr. It is proposed that in both cases the transalkylation processes are acid catalyzed, the residual water molecules and the surface oxygen being the active spots recycling the protons in montmorillonite and zeolite, respectively." @default.
