What is 1,2-Dibromo-1-chloro-1,2,2-trifluoroethane?

The Uses of 1,2-Dibromo-1-chloro-1,2,2-trifluoroethane

1,2-Dibromo-1-chloro-1,2,2-trifluoroethane (BCTFE) is an important fluorine-containing organic intermediate that can be used in pesticides, medicines, materials and other fields.

Synthesis

In a 250ml three-necked round-bottomed flask, add 100g of 1,2-dibromo-1-chloro-1,2,2-trifluoroethane and 100g of liquid bromine (0.626mol), and magnetically stir the reaction system at 25°C. Stir. Slowly pass chlorotrifluoroethylene gas into the reaction system until the red-brown color of the reaction system fades. After the reaction was completed, insoluble impurities were removed by suction filtration, and the solution was purged with nitrogen to remove excess chlorotrifluoroethylene to obtain 266.21g of a colorless transparent liquid (1,2-Dibromo-1-chloro-1,2,2-trifluoroethane).
