- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Boiling pt.:
- 333 °C
- Atm. press.:
- 1 013.3 hPa
- Remarks on result:
- other: see 'Remarks'
- Remarks:
- Mean of the on-set temperature of 3 determinations.
- Conclusions:
- The test item has a boiling point of 333 °C (mean of the offset-temperatures of three determinations).
- Executive summary:
The boiling point of the sample was tested according to EU Method A.2 and OECD Guideline 103 in a GLP study. The boiling point of the test item at atmospheric pressure (1013.3 hPa) is 333 °C (mean of the offset-temperatures of three determinations). This was confirmed by an additional measurement with the capillary method, where rapid gas bubbles were observed at the indicated boiling point.
Reference
Three measurements in aluminium crucibles with a hole showed an endothermic effect after melting in the temperature range 315 - 380 °C with an onset temperature of 333 °C.
For the correction ∆t of the boiling point to standard atmospheric pressure (1013.3 hPa) the equation, table and graphs of H.B. Hass and R.F. Newton in „CRC Handbook of Chemistry and Physics, 74th ed. 1993-1994", pages 15-16 and 15-17 were used.
An additional measurement with the capillary method was performed to clarify the results of the DSC measurements.
Description of key information
The boiling point of the sample was tested according to EU Method A.2 and OECD Guideline 103 in a GLP study. The boiling point of the test item at atmospheric pressure (1013.3 hPa) is 333 °C (mean of the offset-temperatures of three determinations). This was confirmed by an additional measurement with the capillary method, where rapid gas bubbles were observed at the indicated boiling point.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 333 °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.
