- Investigations by differential scanning calorimetry (DSC) provide information on the thermal behavior of substances. Samples of the test substance and of a reference material are subjected to the same controlled temperature programme; they are heated in an oven at a constant heating rate, and the temperatur is measured in two containers. The difference in energy input necessary to maintain identical temperatures between the substance and the reference material is recorded. When the sample undergoes a phase transition, the corresponding change of enthalpy gives a departure form the base line of the heat flow record.
The DSC is mainly used as screening method for thermal stability analysis to determine the beginning of decomposition (onset temperature) and the heat of decomposition. - GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Boiling pt.:
- 305.07 °C
- Atm. press.:
- 99.8 kPa
- Decomposition:
- no
- Remarks on result:
- other: Mean value of three measurements
- Boiling pt.:
- 305.8 °C
- Atm. press.:
- 101.325 kPa
- Decomposition:
- no
- Remarks on result:
- other: value corrected to standard pressure
- Conclusions:
- boiling point = 305.07 °C at 99.8 kPa
boiling point corrected to standard pressure (101.325 kPa) = 305.8 °C - Executive summary:
The boiling point of the test substance was determined to be 305.07 °C at 99.8 kPa by using differential scanning calorimetry (2012, non-GLP); the boiling point corrected to standard pressure (101.325 kPa) is 305.8 °C.

Description of key information
The boiling point of the test substance was determined to be 305.07 °C at 99.8 kPa by using differential scanning calorimetry (2012, non-GLP); the boiling point corrected to standard pressure (101.325 kPa) is 305.8 °C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 305.8 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
