Kinetics and Mechanism of the Thermal Reaction between Perfluorobutene-2 and Trifluoromethylhypofluorite

The kinetics of the thermal reaction between CF3OF and C4F8 have been investigated in the range of 30 deg C to 90 deg C.It was found to be a homogeneous chain reaction of moderate length.The main product is CF3CF(OCF3)CF2CF3, accompanied by small amounts of C8F18, CF3OOCF3 and CF3CF(OCF3)CF(OCF3)CF3 in constant ratio.Traces of (CF3CF(OCF3)CFCF3)2 are also formed.Inert gases and reaction products have no influence on the reaction, whereas small amounts of oxygen change its course.Under conditions in which / > 1, the reaction follows a second order rate expressi on - = k.The following mechanism explains the experimental results .The chain length ν = /2 is found to be ν = 19+/-3 in the range 32 deg C to 92 deg C, the rate constant of the starting reaction k1 = (5.34+/-0.30)106exp(-13.9 kcal*mol-1/RT)l*mol-1*s-1. - Keywords: Kinetics / Thermal reaction / Perfluorobutene-2 / Trifluoromethylhypofluorite / Perfluoroalkyl radicals
