Rate constants for the reactions of O 3 and OH radicals with furan and thiophene have been determined at 298 ± 2 K. The rate constants obtained for the O 3 reactions were (2.42 ± 0.28) × 10 −18 cm 3 /molec·s for furan and <6 ×10 −20 cm 3 /molec·s for thiophene. The rate constants for the OH radical reactions, relative to a rate constant for the reaction of OH radicals with n ‐hexane of (5.70 ± 0.09) × 10 −12 cm 3 /molec·s, were determined to be (4.01 ± 0.30) × 10 −11 cm 3 /molec·s for furan and (9.58 ± 0.38) × 10 −12 cm 3 /molec·s for thiophene. There are to date no reported rate constant data for the reactions of OH radicals with furan and thiophene or for the reaction of O 3 with furan. The data are compared and discussed with respect to those for other alkenes, dialkenes, and heteroatom containing organics.
