Reaction Conditions:

with potassium fluoride;triethylamine in acetonitrile at 40; under 0 - 7500.75 Torr; for 8 h;Inert atmosphere;

Steps:

1 Synthesis of hexafluoropropylene dimer (DHFP)

First, the reaction system is heated and vacuumed to remove water, and the entire system is purged with high-purity nitrogen to remove oxygen.Cool the reaction kettle to room temperature, add acetonitrile solvent (41g, 1mol) into the reaction kettle,Triethylamine (10.1g, 0.1mol) and catalyst potassium fluoride (5.81g, 0.1mol), and then metered into hexafluoropropylene (150g, 1mol)Control the temperature in the kettle at 40°C, the pressure at 0-1Mpa, and keep it warm for 8 hours.After the reaction was completed, hexafluoropropylene dimer (144 g, 0.96 mol) was obtained by distillation, with a yield of 96%.
