- Conclusions:
- The test item has a boiling point of 187.5 °C at atmospheric pressure (1013 hPa).
- Executive summary:
The boiling point of the test item was determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995). Two replicate measurements were performed and the test item was found to have a boiling point of 187.5 °C corrected to normal atmospheric pressure (1013 hPa).
Reference
The test item showed an endothermic signal in the temperature range of approx. 110–200 °C that can be assigned to the boiling of the test item.
| Replicate | amount of test item (mg) | Onset of effect (°C) | Range of effect (°C) | weight loss (mg) | Atmospheric pressure (hPa) |
| 1 | 14.17 | 187.76 | 110 - 200 (endo) | 14.17 | 1017.1 |
| 2 | 14.08 | 187.4 | 110 - 200 (endo) | 13.98 | 1014.0 |
For the correction of the boiling temperature to standard pressure the test item was assigned to chemical group 3 (e.g. Esters). Accordingly a correction value φ= 5.15 was used for the temperature range of 180–190 °C.
The lowest measured onset temperature is corrected to the standard pressure to be 187.37 °C and the highest onset temperature to be 187.61 °C. As the corrected onset temperatures in both tests deviate by less than 0.5 K from their mean value of 187.49 °C, the test item has a boiling point of 187.5 °C.
No further thermal effects were observed up to the maximum test temperature of 500 °C.
Description of key information
The test item has a boiling point of 187.5 °C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 187.5 °C
Additional information
One experimental study assessing the boiling temperature by differential scanning calorimetry, according to OECD Test guideline 103 and EC No. 440/2008 Method A.2 is available. This study has been used as key study for this endpoint. The results taken from two renowned reference handbooks, CRC Handbook and the Merck Index, were used as supporting evidence.
According to the experimental study, the test item has a boiling point of 187.5 °C, which is well in line with the results found in CRC Handbook, 187°C, and the Merck Index, 189 °C.
