The addition of methyl radicals to tetrafluoroethylene in the gas phase has been studied over the temperature range 8O-18O0C, using a material balance method. CH, + C,F4 -+ CH,C,F, Arrhenius parameters of 1011.95\*0.23 (mole-l cm3 sec-l) and 5.7 f 0.4 (kcal/mole) have been measured for the addition
## Abstract The addition of methyl radicals to hexafluoropropylene has been studied over the temperature range 81Β°β203Β°C using a massβbalance technique involving the photolysis of biacetyl in the presence of hexafluoropropyleneβisobutane mixtures. For the reaction the rate constant is given by th
The reactions have been studied by a mass-balance method involving the photolysis of small amounts of biacetyl in the presence of a large excess of isobutane containing a small proportion of the unsaturated substrate. The following Arrhenius parameters have been derived: Temperature Reaction E log A
