The kinetics of the reaction of CCl2 with molecular chlorine has been studied using the laser photolysis/photoionization mass spectrometry technique. Dichloromethylene biradicals were produced by the pulsed laser photolysis of carbon tetrachloride, and the kinetics of their decay due to reaction with Cl-2 were monitored in direct time-resolved experiments. Rate constants were determined as a function of temperature (300-750 K) and can be described by the Arrhenius expression k(1) = (1.3 +/- 0.3) x 10(-11) exp(-(281 +/- 96) KIT) cm(3) molecule(-1) s(-1). Rate constants of reaction 1 are independent of the bath gas density within the experimental range [He] = (3-12) x 10(16) atoms cm(-3). CCl3 was observed as a primary product of the reaction.
