Реферат:
The liquidphase interaction between isobutane and butenes at 303 K and 2.5–3.0 MPa has been investigated 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 catalytically active aluminum chloride complexes forming in situ in the hydrocarbon medium vary in composition. 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 AlCl4– and Al2Cl7– 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, isobutane undergoes selfalkylation. In this case, the Al2Cl7– ion is not detected and the most abundant complexes are AlCl4–, Al3Cl10– , and the molecular species AlCl3 ⋅ tertC4H9Cl. It is hypothesized that the Al2Cl7– ion plays the key role in the liquidphase alkylation of isobutane with butenes.
