✦ Synopsis

Rate constants for the reactions of 0 3 and OH radicals with furan and thiophene have been determined at 298 f 2 K. The rate constants obtained for the 0 3 reactions were (2.42 f 0.28) X 1O-lS cm3/molec.s for furan and <6 X cm3/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 f 0.09) X cm3/molec.s, were determined to be (4.01 f 0.30) X lo-" cm3/molec.s for furan and (9.58 f 0.38) X 10-l2 cm3/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 0 3 with furan. The data are compared and discussed with respect to those for other alkenes, dialkenes, and heteroatom containing organics.
