Bromine material factor

Formation of dioxins/furans A compound containing standard loadings of decaBDPE was injection moulded and reground to simulate recycling. After five cycles the material was analysed for brominated dioxins and fiirans. The compound showed no detectable amounts and the recycled forms showed levels below the limit of the German Dioxin Decree by a factor of about 40. 

Analysis Weigh the distillate and determine the yield of products. Test the distillate for unsaturation using the bromine and Baeyer tests (Secs. 25.8A and B. respectively). Analyze your distillate by GLC or submit a sample of it for analysis. After obtaining the results, calculate the relative percentages of the isomeric alkenes formed assume that the response factors are identical for the isomers. A typical GLC trace of the alkenes from this elimination is shown in Figure 10.10. Obtain IR and NMR spectra of your starting material and compare your spectra with those of an authentic sample (Figs. 10.11 and 10.12). 

The standard open circuit potential of bromine/polysulphide RFBs reaches 1.515 V, but in practical applications, it depends on many factors, including electrode material, electrolyte composition, operating temperature, and state of charge.
