Photochemical Reactions in Gaseous Mixtures of C2F4 and CF3I

Products of photochemical reactions occurring in gaseous mixtures of C₂F₄ and CF₃I under vacuum-UV irradiation were studied. The major photolysis products are linear perfluoroparaffins C _n F_2n+2 and linear perfluoroalkyl iodides C _n F_2n+2I. The product ratio is consistent with the suggested kinetic scheme of chain reactions of telomers.     

Photolysis of Perfluoropropylene-Methanol Mixture in Vacuum Ultraviolet

The products of reaction of C₃F₆ with CH₃OH, initiated by vacuum ultraviolet, were determined. The kinetics scheme of the process was proposed. The parameters of the kinetic processes were calculated. The feasibility of photochemical preparation of 2,2,3,4,4,4-hexafluoro-1-butanol was analyzed.
