Figure 3
Thermogravimetric analyses of H2dazolBr2 (%weight versus T) together with IR characteristics of the evolving gases at temperatures as indicated. Heating of the sample (a) in a steady stream of N2 only and (b) in a 1:1 mixture of N2 and O2. The inset in (b) shows an enlargement for the range 2400–2700 cm−1, indicating the formation of HBr in small traces. |
