Reaction Conditions:

with nitrogen trifluoride at 430; under 750.075 Torr;Gas phase;Temperature;Pressure;

Steps:

3
100 L of cobalt fluoride was charged into the tubular reactor,The temperature of the reactor was controlled to 430 ° C,Pressure is O.IMPa,And then a mixed gas of nitrogen trifluoride of 3.87 L / min and nitrogen of 193.5 L / min was added,A flow rate of 2.58 / min of pentafluoroethane,at this time,The gas space velocity in the cobalt oxide layer was 2 / min,After the reaction product comes out from the reactor,To obtain the hexafluoroethane.The reaction product obtained above was analyzed by gas chromatography, and the results of the analysis are shown in Table 3. Calculated, hexafluoroethaneThe yield of the alkane was 79%.
