Thermal degradation study of tetrabromobisphenol A under the presence metal oxide: Comparison of bromine fixation ability

Thermal degradation of mixture of tetrabromobisphenol A (TBBA) and metal oxide (ZnO, Fe2O3, La2O3, CaO and CuO) has been studied under inert atmosphere. The formation of hydrogen bromide and brominated organic compounds is observed for pyrolysis of TBBA. The addition of metal oxide gives rise to considerable suppression of HBr as well as brominated organic compounds. The suppression owes to the bromination of oxides. The influence of oxide on thermal degradation of TBBA is discussed with emphasis on the conversion of bromine.
