Notes

Abstract: The high-temperature fast-flow reactor (HTFFR) technique has been used to measure rate coefficients for the title reactions under pseudo-first-order conditions. The relative concentrations of the minor reactants (Al species) were monitored by laser-induced fluorescence. The following k(T) expressions in cm³ molecule⁻¹ s⁻¹ are obtained: Al + Cl₂ → AlCl + Cl, k₁(T) = 7.9 x 10⁻¹⁰ exp(-780K/T) between 425 and 875 K; Al + HCl → AlCl + H, k₂(T) = 1.5 x 10⁻¹⁰ exp(-800K/T) between 475 and 1275 K; AlCl + Cl₂ → AlCl₂ + Cl, k₃(T) = 9.6 x 10⁻¹¹ exp(-610K/T) between 400 and 1025 K. Confidence limits are given in the text. Indications are obtained that the expressions for k₁(T) and k₂(T) are approximately valid to at least 1300 and 1700 K, respectively. The results are discussed in terms of a harpooning mechanism and a modified form of collision theory, which takes account of long-range attractive potentials and conservation of angular momentum.
