Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Boiling point at 101 325 Pa:
251.7 °C

Additional information

The determination of the boiling point of test item was performed via DSC (differential scanning calorimetry) according to the OECD Guideline 103 and EU Method A.2. Three endothermic events were detected. The second event was indicated as the melting point and the third as the boiling point. The first event is supposed to be a solid to solid transition.

The first event was determined in a range of: -19.00 – -18.12 °C (254.15 – 255.03 K)

The second event the melting point was determined in a range of: 27.21 – 29.56 °C (300.36 – 302.71 K)

The last event the boiling point of the test item was determined in a range of: 251.70 – 252.20 °C (524.85 – 525.35 K)
