Atmospheric pressure: 101.1 kPa

Mean boiling temperature: 296.0 ± 0.5 °C (569.1 ± 0.5 K)

Preliminary screening testing in air and in a nitrogen atmosphere indicated that the test item

boiled at approximately 300 °C (573 K) at 100.5 to 100.6 kPa.

Applicant's summary and conclusion

Conclusions:
The boiling point of the test item has been determined to be 296.0 ± 0.5 °C (569.1 ± 0.5 K) at 101.1 kPa.
Executive summary:

The boiling point of the test item has been determined to be 296.0 ± 0.5 °C (569.1 ± 0.5 K) at 101.1 kPa, by differential scanning calorimetry, designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD

Guidelines for Testing of Chemicals, 27 July 1995.
