Synthesis of Highly Deactivated Polyhalogenated Aromatic Compounds

摘要

The barium fluorobromate(III) was obtained as the product of interaction between barium fluoride and bromine(III) trifluoride. The heat of formation of Ba(BrF_4)_2 was found by isothermal calorimetry method. By the TG/DT analysis the thermal stability of Ba(BrF_4)_2 was researched. It was found that this compound is mostly stable in the atmosphere or argon up to 250 °C. It was shown that bromine trifluoride and its derive compounds with alkali and alkali-earth metals fluorides can be applied like a highly-active brominating agent in case of production of various composite materials based on polyhalogenated aromatics.
