Conclusions

  1. 1.

    The general kinetics of the radical isomerization of 3,3,3-trichloro-2-bromopropene was studied in the interval 293–323°K. In the case of irradiation of 3,3,3-trichloro-2-bromopropene with the complete spectrum of a PRK-4 lamp, the reaction is second order with respect to the starting material, and the summary rate constants satisfy the equation k=79 exp(−9500/RT). In the case of irradiation of the starting material with UV light with wavelength <300μ, the order is first.

     
  2. 2.

    The quantum yield, calculated using the liquid phase actinometer K3Fe(C2O4)3, is ∼103, which indicates a radical chain character of the reaction.

     
  3. 3.

    The mechanisms of initiation and termination of the kinetic chain were studied, and a scheme of the reaction was proposed on the basis of this.
