Reference
A fresh sample was scanned between 150 and 210°C. On inspection of the sample at room temperature, it was seen to be an amber coloured liquid, thus indicating that the first exotherm was a result of some chemical change.
An additional scan was performed between 100 and 300°C to enable measurement of the onset temperatures. Upon cooling the sample to room temperature, it was seen to be a deep amber-coloured liquid. The onset of chemical change occurred at 164°C, with the extrapolated onset temperature being 176°C.
When a fresh sample was scanned under an atmosphere of nitrogen, no exotherms were produced. This indicated that oxidative degradation processes were occuring.
Description of key information
PBO does not possess a boiling temperature at 101 325 Pa, but it undergoes chemical change from 164°C (EU Method A.2 (Boiling Temperature); EOECD Guideline 103 (Boiling point/boiling range)
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 164 °C
Additional information
The boiling temperature was assessed using differential scanning calorimetry, is a technique that records the difference in energy inputs into a substance and a reference material, as a function of temperature (°C), while the substance and reference material are maintained at identical temperatures.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
