WebAn interesting difference in the CHF3 pyrolysis results as compared to the results obtained using CHClF2 is the relative lack of CHF2CHF2 as a product in the CHF3 pyrolysis. This lack of observation of CHF2CHF2 in the CHF3 pyrolyses is undoubtedly the result of its H2-promoted isomerization to CF3CH2F at these high temperatures. WebApr 30, 2007 · Abstract.
