摘要：NOVELTY - A 1-bromo-2-iodo-tetrafluoroethane is prepared by in presence of organic solvent or inorganic solvent, reacting tetrafluoroethylene and iodobromide at 50-80 degrees C and 0.1-2.0 MPa via gas-liquid phases, and obtaining 1-bromo-2-iodo-tetrafluoroethane. Organic solvent is 2-4C fluorine-containing halogenated hydrocarbon whose boiling point is higher than that of 1-bromo-2-iodo-tetrafluoroethane, or 2-4C halogenated hydrocarbon with hydrogen and fluorine. USE - Method for preparing 1-bromo-2-iodo-tetrafluoroethane (claimed). ADVANTAGE - The product has high selectivity, and easy separation and purification. It has purity of 97% and price is relatively low.
