- Key result
- Boiling pt.:
- >= 243 - <= 365 °C
- Atm. press.:
- 101 kPa

- The boiling temperature of the test item has been determined to be from approximately 243 °C (516 K) at 101 kPa.
- Executive summary:
GUIDELINE
The determination was carried out by differential scanning calorimetry, using a procedure designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
DISCUSSION
The test materials is a complex mixture (UVCB) that was found to boil over a broad temperature range with two distinct endotherms. The onset of boiling was taken as the starting point of the endotherms. At 310°C approximately 50 % of the sample had been lost whereas 100 % was lost by 365°C.
CONCLUSION
The boiling temperature of the test item has been determined to be from approximately 243 °C (516 K) at 101 kPa.
