Abstract

The reaction Cl+CH₃CHO→HCl+CH₃CO (1) was studied using flash photolysis/tunable diode laser absorption spectroscopy to monitor the production of HCl. The rate coefficient, k₁, was measured to be (7.5±0.8)×10^-11 cm³ molecule^-1s^-1 at 298 K HCl (v = 0) and HCl (v = 1) were measured directly in this study and the yields of HCl (v = 0, 1>1) for the reaction of Cl with CH₃CHO were determined to be 0.44±0.15, 0.56±0.15, and <0.04, respectively. The rate coefficient for the quenching of HCl (v = 1) by CH₃CHO was k_17e = (4.8±1.21×10^-11cm³ molecule^-1s^-1.
