Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
26-27 January 2022
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
The study was conducted according to an internationally recognised method, with no deviation, and under GLP. The test substance is adequately characterised. Therefore full validation applies.
Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)
Version / remarks:
Commission Regulation (EC) No 440/2008
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling Point)
Version / remarks:
27 July 1995
GLP compliance:
yes (incl. QA statement)
Remarks:
GIPC GLP compliance (inspected on 18 -20 August 2020, signed on 17 Mars 2021)
Type of method:
differential scanning calorimetry
Key result
Boiling pt.:
177 °C
Atm. press.:
101.3 kPa
Decomposition:
no
Remarks on result:
other: Average value of duplicate determinations. The crucible was visually checked after both the determinations. By opening the crucible, traces of test item left in the crucible but no sign of decomposition was observed.

First Determination


Mass taken: 11.32 mg


Initial boiling point was observed at 176.3°C (onset temperature of the peak) and a mass loss of 91.42% was observed between the beginning and the end of the boiling peak.


Atmospheric pressure: 99.3 kPa.


Second Determination


Mass taken: 10.96 mg


Initial boiling point was observed at 176.2°C (onset temperature of the peak) and a mass loss of 92.18% was observed between the beginning and the end of the boiling peak.


Atmospheric pressure: 99.3 kPa.


Sydney-Young Correction


The corrected values following Sidney-Young equation were determined to be 177.0°C at 101.3 kPa for the first determination and 176.9°C at 101.3 kPa for the second determination.

Conclusions:
After correction using the Sydney Young equation, the initial boiling point of the substance was determined as 177.0°C at 101.3 kPa.
Executive summary:

The boiling point of the test substance was determined under GLP according to OECD 103 / EU A2 guideline, using the DSC method.



Two main runs were performed, under inert atmosphere.


After correction using the Sydney Young equation, the initial boiling point of the substance was determined as 177.0°C at 101.3 kPa (mean of 177.0°C for the first determination and 176.9°C for the second determination).

Description of key information

Under consideration of the results from DSC measurements it was concluded that the mean onset for boiling occured at 177.0 °C at 101.3 kPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
177 °C

Additional information

A fully reliable experimental study, conducted according to a recognised OECD/EC method and under GLP, is available.
It is considered as a key study, and the result is retained as key data.
