Experimental and transition-state theory studies of the gas-phase reactions of monochloroaluminum with nitrous oxide, carbon dioxide, and sulfur dioxide

Abstract

The high-temperature fast-flow reactor technique has been used to make kinetic measurements. A weighted fit to the AlCl+N 2 O data gives k(700-990 K)=5.6×10 -11 exp(-7380 K/T) cm 3 molecule -1 s -1 . A weighted fit to the AlCl+CO 2 measurements leads to the expression k(900-1790 K)=4.4×10 -23 (T/K 3.0 exp(-3900 K/T) cm 3 molecule -1 s -1 . 2σ accuracy limits are about ±25%. An upper limit k(800-1100 K)<5×10 -14 cm 3 molecule -1 s -1 has been determined for the AlCl+SO 2 reaction
