MORONTA, A., TAYLOR, S. and BREEN, C. (2002). Adsorption of olefins on aluminum- and aluminum/tetramethyl-ammonium-exchanged bentonites. Clays and Clay Minerals, 50 (2), 265-271.Full text not available from this repository.
One montmorillonite, STx-1 (Texas, USA), was activated with different amounts of Al and tetratnethylammonium (TMA(+)) canons to obtain materials with a combined Al3+ and TMA(+) content equal to its cation exchange capacity. The adsorption capacity of these samples was studied saturating them with hept-1-ene at room temperature. The samples were heated and the evolved gases analyzed by Fourier transform infrared spectroscopy and gas chromatography-mass spectrometry. Hept-1-ene reacted with the clays via proton transfer and resulted in the formation of a variety of reaction products (>60 hydrocarbons). In general, the presence of TMA(+) cations significantly reduced the population of protons to selectively produce isomerization and hydration products.
