Remarks on result:

other: mean of 2 replicate measurements

During the heating phase, an endothermic effect in the temperature range of 50 to 70°C was observed, which can be assigned to the melting of the test item. A second endothermic signal was observed in the range of 300 -410°C.

The results of the 2 replicate measurements are:

Replicate	sample weight (mg)	Onset of effect (°C)	Range of effect (°C)	Weight loss (mg)	Atmospheric pressure (hPa)
1	8.99	328.11	300 to 405 (endo)	8.72	1005.2
2	10.87	327.70	300 to 405 (endo)	10.66	1005.2

For the correction of the boiling temperature to standard pressure the test item was assigned to chemical group 3 (e.g. Esters): correction value φ= 5.5 was used for the temperature of 330 °C.

As the corrected onset temperatures in both tests deviate by less than 0.5 K from their mean value of 328.29 °C, the test item has a boiling point of 328.3 °C.

Conclusions:

The test item has a boiling point of 328.3 °C corrected to normal atmospheric pressure (1013 hPa).

Executive summary:

The boiling point of the test substance was assessed according to OECD 103, differential scanning calorimetry. Two replicate measurements were performed. The test item was found to have an endothermic signal in the temperature range of 300 -450°C. After correction to the standard pressure, the mean corrected boiling point was found to be 328.3°C.

Description of key information

The test item has a boiling point of 328.3 °C corrected to normal atmospheric pressure (1013 hPa), as determined according to OECD 103, differential scanning calorimetry.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

328.3 °C

Additional information

In a recent study the boiling temperature of the test item was determined according to the OECD 103 by DSC (differential scanning calorimetry). A thermogram is obtained in which the transition heat flow is exhibited as function of the temperature. In this diagram, the onset of the process as well as the heat flow of the process are shown.

The test item has a boiling point of 328.3 °C corrected to normal atmospheric pressure (1013 hPa).
