Reaction Conditions:

in dichloromethane at -10 - 20; for 10 h;Overall yield = 33.7 g;

Steps:

4 Example 4
Example 4 (0045) This example is representative of the production of reaction mixture (VI). (0046) At room temperature, 100 ml dichloromethane and 17.7 ml diethylamine are loaded in a flask. (0047) It is cooled to T=-10° C. and, under stirring, 32.5 g hexafluoropropene are made to be absorbed by the solution over 10 hours. (0048) The GC check shows the complete disappearance of diethylamine from the reaction mixture. (0049) Dichloromethane is distilled at reduced pressure obtaining 33.7 g of reactive mixture (VI) which at the GC check shows the virtually exclusive presence of the two fluorinated components with 49.94 and 48.46% areas. (0050) Such a mixture can be used as such without need for subsequent purifications.
