Pyrolysis of tetrafluoroethylene

Abstract : The pyrolysis of tetrafluoroethylene was studied in the temperature and pressure range 300 to 455C and 25 to 760 torr. The rate of reaction was determined to be second order with respect to the tetrafluoroethylene, and three independent numerical values of the second order rate constant were determined by simultaneously measuring the tetrafluoroethylene concentration, the octafluorocyclobutane concentration and the total pressure as a function of reaction time. The temperature dependence of the reaction rate constants are given. (Author)
