Reaction Steps

700 ml of ethylene glycol and 65 g of 1,2-bis(4-fluorophenyl)-1,1,2,2-tetrafluoroethane* are heated to 110° C. in a stirred flask. 57 g of potassium tert.-butylate are added in portions and the mixture is then stirred at 150° C. for 7 hours. The mixture is cooled, poured onto 4 liters of ice-water and mixed thoroughly with a homogenizer (Ultraturax). The crystals which have precipitated are filtered-off with suction, stirred again with 2 liters of water filtered-off with suction again, dried and recrystallized from toluene.
