The Thermal Gas-phase Decomposition of Vinyl Bromide

Abstract
The thermal gas-phase decomposition of vinyl bromide in Ar has been studied behind reflected shock waves over the temperature range between 1300 and 2000 K and the density range of 5.2×10−6–3.8×10−5 mol cm−3 by monitoring the UV absorption of C2H3Br and the IR emission of HBr. The decomposition proceeds via the molecular elimination of HBr, and the unimolecular process is in the low-pressure region under the present experimental conditions. The low-pressure-limit rate constant was obtained as
