It is a decomposition product of halon compounds used in fire extinguishers. ==Reactions== Carbonyl bromide is formed when carbon tetrabromide is melted and concentrated sulfuric acid is added. In contrast to phosgene, carbonyl bromide cannot be produced efficiently from carbon monoxide and bromine. A complete conversion is not possible due to thermodynamic reasons. Additionally, the reaction CO + Br2 <-> COBr2 processes slowly at room temperature. Increasing temperature, in order to increase the reaction rate, results in a further shift of the chemical equilibrium towards the educts (since ΔRH < 0 and ΔRS < 0).〔https://books.google.de/books?id=fM43Ny2eFS8C&pg=PA900&lpg=PA900&dq=carbonyl+bromide+enthalpy+of+formation&source=bl&ots=-ny9U7I-bx&sig=4XDedlqIFEK2OtXizrJaUfkBdzI&hl=de&sa=X&ei=UEgoVYCmI86uabvrgLAK&ved=0CDwQ6AEwAw#v=onepage&q=carbonyl%20bromide%20enthalpy%20of%20formation&f=false, pp. 669-671, retrieved 2015-04-11〕 On the other hand, carbonyl bromide slowly decomposes to carbon monoxide and elemental bromine even at low temperatures.〔 〕 It is also sensitive to hydrolysis. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Carbonyl bromide」の詳細全文を読む スポンサード リンク
