Rate constant of the reaction of chlorine atoms with methanol over the temperature range 291–475 K

Abstract

The rate constant of the reaction Cl + CH 3 OH ( k 1 ) has been measured in 500–950 Torr of N 2 over the temperature range 291–475 K. The rate constant determination was carried out using the relative rate technique with C 2 H 6 as the reference compound. Experiments were performed by irradiating mixtures of CH 3 OH, C 2 H 6 , Cl 2 , and N 2 with UV light from a fluorescent lamp whose intensity peaked near 360 nm. The resultant temperature-dependent rate expression is k 1 = 8.6 (±1.3) × 10 −11 exp[−167 (±60)/T] cm 3 molecule −1 s −1 . Error limits represent data scatter (2Σ) in the current experiments and do not include error in the reference rate constant. © 2009 Wiley Periodicals, Inc. Int J Chem Kinet 42: 113–116, 2010
