| 热分解说明 : | When heated to decomposition it emits toxic vapors of bromide.；1,2-bis-(2,4,6-tribromophenoxy)ethane (BTBPE) is currently one of the most utilised novel brominated flame retardants. In this contribution, ... the mechanisms pertinent to its thermal decomposition in view of analogous experimental findings /were analyzed in detail/. ... A 1,3-hydrogen shift, leading to 2,4,6-tribromophenol (M9) and 1,3,5-tribromo-2-(vinyloxy)benzene (M10) molecules, dominates direct scission of O-CH2 bonds up to a temperature of ~ 680 K /was demonstrated/. H atom abstraction from CH2 sites, followed by a fission of a C-C bond, produces a 2,4,6-tribromophenoxy radical (M2) and a M10 molecule. Bimolecular condensation reactions involving M2, M9 and M10 produce several congeners of brominated diphenyl ethers and their OH/OCHCH2 substituents, which serve as direct precursors for the formation of polybrominated dibenzo-p-dioxins. Reaction of M9 with a model compound of a hydrocarbon chain preferentially yields M2. Strong adsorption energy of the latter on a radical site of a hydrocarbon chain suggests that mechanisms such as Langmuir-Hinshelwood, Eley-Rideal and Diels-Alder might be operating during the formation of PBDD/Fs from brominated flame retardants (BFRs). |
