Abstract

Measurements of the rate constant for the gas phase reactions of OH radicals with trans-1-chloro-3,3,3-trifluoropropene (trans-CHCl=CHCF3) were performed using a flash photolysis resonance-fluorescence technique over the temperature range 220 K to 370 K. The temperature dependence of the rate constant can be represented by the following expression: k(220 - 370 K) = 1.025*10^(-13)*(T/298)^2.29*exp{+348/T}, cm3 molecule-1 s-1. The atmospheric lifetime of trans-CHCl=CHCF3 due to reaction with tropospheric OH was estimated to be 46 days under assumption of the compounds being well mixed throughout the atmosphere. UV and IR absorption cross sections of this compound were measured at room temperature. The GWP and ODP of the compound were estimated and discussed.
