The authors have used the relative rate technique to study the reaction of Cl atoms with a number of unsaturated species, including isoprene, methacrolein (MACR), methyl vinyl ketone (MVK), 1,3-butadiene, trans-2-butene, and 1-butene. Reactions were carried out at room temperature in synthetic air and/or nitrogen. Numerous products in the Cl atom initiated oxidation were identified and mechanistic discussion is provided.
Absolute rate coefficients were derived in conjunction with recommended values for the reaction of Cl with propane, k = 1.43 ?10-10 cm3 molecule-1 s-1 (independent of pressure), propene, k = 2.63 ?10-10 cm3 molecule-1 s-1 (at 700 Torr total pressure), and/or ethene, k = 0.99 ?10-10 cm3 molecule-1 s-1 (at 700 Torr total pressure).
Absolute value was derived relative to the reaction C3H6 + Cl = PRODUCTS. Uncertainties are 1 standard deviation and are precision only.
