Diethylamine → 1,1,2,2-Tetrafluoroethyldiethylamine

1,1,2,2-tetrafluoroethyldiethylamine is prepared by the addition of tetrafluoroethylene at pressures of up to 700 kPa (100 psig) to an agitated solution of diethylamine. Equipment used for this preparation consists of a one liter bomb in a barricaded rocker arm, on account of the explosive nature of tetrafluoroethylene at elevated pressures. The reaction is carried out between 25 and 91° C. The obtained crude product is fractionated at 14 kPa of pressure (100 mm Hg) to yield a liquid product having a boiling point between 70 and 90° C.
