摘要：

Rate coefficients were determined for the reactions of the furanones (C6H10O2) (C7H12O2) with OH radicals (k(1) and k(2)) and with Cl atoms (k(3) and k(4)) at 298 K, to be (in cm(3) molecule(-1) s(-1)): k(1) = (6.4 +/- 1.4) x 10(-12), k(2) = (8.8 +/- 1.9) x 10(-12), k(3) = (1.30 +/- 0.41) x 10(-10), k(4) = (1.70 +/- 0.34) x 10(-10), respectively. k(OH) correlates with k(Cl) and SAR show C5 as the favored site of H abstraction.
