While cooling down, an exothermic effect was detected in the temperature range of -70 to -80 °C which can be assigned to the freezing of the test item.

During heating up, a first endothermic effect (melting) was observed in the temperature range of -50 to -30°C. In the temperature range of 100 – 130 °C a second endothermic effect (boiling) was detected.

The boiling point was corrected to standard pressure of 1013 hPa.

The lowest measured onset temperature 119.86 °C is corrected to standard pressure to be 119.58 °C and the highest onset temperature 120.41 °C to be 120.14 °C. As the corrected onset temperatures in both tests do not deviate by more than 0.5 K from their mean value of 119.86 °C, this temperature can be specified as boiling point of the test item. The test item has a boiling point of 119.9 °C.

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

Conclusions:

The corrected boiling point of the test item was determined to be 119.9 °C at 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). The test item was cooled down to -90 °C and then heated up to 500 °C at a constant heating rate of 10 K/min under air. The test item showed an endothermic effect in the temperature range of 100 – 130 °C, which can be assigned to the boiling of the test item. The boiling point was corrected to standard pressure of 1013 hPa. As the corrected onset temperatures in both tests do not deviate by more than 0.5 K from their mean value of 119.86 °C, this temperature can be specified as boiling point of the test item. The corrected boiling point of the test item was determined to be 119.9 °C at 1013 hPa.

Description of key information

The corrected boiling point of the test item was determined to be 119.9 °C at 1013 hPa (reference 4.3-1).

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
