Key result
Boiling pt.:
295.9 °C
Atm. press.:
1 013 hPa

Detailed results:

Replicate sample weight (mg) Onset of effect (°C) Range of effect (°C) Weight loss (mg) Atmospheric pressure (hPa)
1 18.19 295.73 170-320 (endo) 18.13 1003.8
2 16.69 295.09 160-310 (endo) 16.66 1001.4

For the correction of the boiling temperature to standard pressure the test item was assigned to chemical group 2 (e.g. Hydrocarbons). According to appendix 8.2 a correction value φ= 5.15 was used for the temperature of 290300 °C.

The lowest measured onset temperature is corrected to the standard pressure to be 295.65 °C and the highest onset temperature to be 296.18 °C. As the corrected onset temperatures in both tests deviate less than 0.5 K from their mean value of 295.92 °C, the test item has a boiling point of 295.9 °C.

No further thermal effects were observed up to the maximum test temperature of 500 °C.

The boiling point of the test item was found to be 295.9°C, corrected to normal atmospheric pressure of 1013 hPa.
Executive summary:

The boiling point of the test item was determined by differential scanning calorimetry according to OECD 103. The test item showed a first endothermic signal (melting point) in the temperature range -40 to 20°C and a second endothermic signal, corresponding to boiling point, in the temperature range of 160 -320°C. The boiling point corrected to the standard pressure was found to be 295.9°C. No thermal effect was observed up to a maximum temperature of 500°C.

Description of key information

For this endpoint, one study is available in which the boiling point is determined according to OECD 103. The boiling point of the test item was found to be 295.9°C (corrected to 1013 hPa).

Key value for chemical safety assessment
