<p>In order to isomerize a hydrofluorocarbon with a certain thermodynamic stability (HFC 1) into hydrofluorocarbon with greater thermodynamic stability (HFC 2), the hydrofluorocarbon HFC1 is subjected to a thermal treatment in the presence of hydrogen at a temperature higher than 500 °C. This method which does not require the use of a catalyst is applicable in particular to the isomerization of 1,1,1,2-tetrafluoroethane into 1,1,1,2-tetrafluoroethane.</p> |
