Abstract: The liquidphase interaction between isobutane and butenes at 303 K and 2.5–3.0 MPa has been inves tigated using activated aluminum (Al*)–tertbutyl chloride (TBC) model system (TBC : Al* = 0.35–4 mol/mol). It has been demonstrated by attenuated total reflection FT–IR (ATR–FT–IR) spectroscopy that the cata lytically active aluminum chloride complexes forming in situ in the hydrocarbon medium vary in composi tion. Alkylation as such takes place at equimolar proportions of the reactants (TBC : Al* = 1 : 1) and butenes feed mass flow rate of 5 h–1 per gram of Al*. According to ATR–FT–IR data, the most abundant aluminum complexes resulting under these conditions are the and ions and, probably, the molecular complex AlCl3 ⋅ secC4H9Cl. In a fourfold excess of TBC over Al* at butenes mass feed rate of 2.5 h–1, isob utane undergoes selfalkylation. In this case, the ion is not detected and the most abundant com plexes are , and the molecular species AlCl3 ⋅ tertC4H9Cl. It is hypothesized that the ion plays the key role in the liquidphase alkylation of isobutane with butenes.
