The thermal decomposition of chlorodifluoromethane has been studied at 1.379 X 104-4.826X 104 Pa (2-7 psig) over the temperature range 750-950°C and residence times of 0.1-0.25 s, which is consistent with commercial practice. Within the limits of detectability, no perfluoroisobutylene was produced in these short residence time runs. Reaction mechanisms areproposedwhich include all products and side products identified in the reactor effluent streams by gas chromatography-mass spectroscopy. Arrhenius preexponential factors and activation energies are estimated for each of the reactions using a numerical integration scheme coupled to a Marquardt least-squares estimation algorithm. Operation of the tubular reactor was simulated at three different temperatures using optimal estimates for the parameter values. Changes in product concentration along the tubular reactor then define operating conditions for any desired product mix.
