Abstract

Gas‐phase reactions of ozone with two butenes (1‐butene and isobutene) and two methyl‐substituted butenes (2‐methyl‐1‐butene and 3‐methyl‐1‐butene) have been studied in an indoor chamber at 295–351 K. The O~3~ concentrations were monitored by Model 49C‐Ozone analyzer. The butene concentrations were measured by gas chromatography–flame ionization detector. The Arrhenius expressions of k=3.50×10^−15^e^(−1756±84)/T^ cm^3^ molecule^−1^ s^−1^, k=3.39×10^−15^e^(−1697±52)/T^ cm^3^ molecule^−1^ s^−1^, k=6.18×10^−15^e^−(1822±80)/T^ cm^3^ molecule^−1^ s^−1^, and k=7.24×10^−14^e^−(2741±139)/T^ cm^3^ molecule^−1^ s^−1^ were obtained for the ozonolysis reactions of 1‐butene, isobutene, 2‐methyl‐1‐butene, and 3‐methyl‐1‐butene, respectively. Both the reaction rate constant and activation energy obtained in this work are in good agreement with those reported by using different techniques in the literature. © 2011 Wiley Peiodicals, Inc.
