- Executive summary:
A study was conducted according to OECD test guideline 103, Regulation (EC) No 440/2008 method A.2 and EPA OCSPP test guideline 830.7220 to determine the boiling point of the test item using differential scanning calorimetry. Two tests with about 16 mg of the test item were performed. The substance is a liquid at ambient conditions. Therefore the crucibles were cooled down from ambient temperature to -100 °C with a constant cooling rate of 0.25 K/min under an inert atmosphere and heated up to 500 °C at a constant heating rate of 10 K/min. During the cooling phase, an exothermal effect was observed in the temperature range of approx. -50 to -15 °C, which can be associated with the freezing of the test item. During the heating phase a distinct endothermic effect was observed in the temperature range of -15 to 0 °C, which can be associated with the melting of the test item. The test item showed a second endothermic signal in the temperature range of approx. 170 - 310 °C that can be associated with the boiling of the test item. A correction of the boiling temperature to standard pressure was conducted. The lowest measured onset temperature is corrected to the standard pressure to be 284.61 °C and the highest onset temperature to be 285.37 °C. As the corrected onset temperatures in both tests deviate by less than 0.5 K from their mean value of 284.99 °C, the test item has a boiling point of 285.0 °C.
Reference
During the cooling phase, an exothermal effect was observed in the temperature range of approx. -50 to -15 °C, which can be associated with the freezing of the test item.
During the heating phase a distinct endothermic effect was observed in the temperature range of -15 to 0 °C, which can be associated with the melting of the test item.
The test item showed a second endothermic signal in the temperature range of approx. 170 - 310 °C that can be associated with the boiling of the test item.
For the correction of the boiling temperature to standard pressure the test item was assigned to chemical group 2 (e.g. Hydrocarbons). According to H.N. Hass and R.F. Newton a correction value ϕ= 5.15 was used for the temperature of 280 - 290 °C.
The lowest measured onset temperature is corrected to the standard pressure to be 284.61 °C and the highest onset temperature to be 285.37 °C. As the corrected onset temperatures in both tests deviate by less than 0.5 K from their mean value of 284.99 °C, the test item has a boiling point of 285.0 °C.
No further thermal effects were observed up to the maximum test temperature of 500 °C.
Description of key information
The boiling point of the test item was 285.0 °C at 1013 hPa.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 285 °C
