Process for a decarbromodiphenylethane predominate …

The level of the liquid bromine in the flask covered the end of the dip tube by about 19 mm. Molten diphenylethane (kept at 55°-66° C.) was then added, through the dip tube, beneath the surface of the bromine over a period of about 92 minutes.

Polymers | Special Issue : Advances in Flame Retardant ...

The flame retardants prepared via the alkylation of toluene or diphenylethane with PBBB were found to be not truly polymeric but had high M w > 1400. However, the alkylation of the same aromatic molecules by a mixture of PBBB and TBXDP resulted in polymeric flame retardants with M w > 130,000. Two other polymeric flame retardants were prepared ...

Process for decabromodiphenylalkane predominant …

The reactor was charged with bromine (33,313 pounds, 208.4 moles) and anhydrous aluminum chloride (175 pounds, 1.31 moles). The reactor was then heated to about 54° C. and molten diphenylethane (DPE) (1,636 pounds, 8.98 moles, 99.3 weight percent DPE) was added through a dip-tube to the reactor contents. The addition of DPE took about 4 hours.

Pyrolysis of WEEE plastics - ScienceDirect

When pyrolysed with 20% of PET, nearly 50% of bromine is confined in gases as inorganic bromide (Bhaskar et al., 2004a). If PVC is added to polyolefins and PET mixture, formation of SbBr 3 is prevented and a large amount of organic bromine/chlorine is found in the oil (Bhaskar et al., 2004b). 11.4.2. Pyrolysis of real WEEE
