Thermatographic data shown in the attached document

Conclusions:
The test item did not boil up to 400 °C (673 K) at 101.5 kPa by differential scanning calorimetry.
Executive summary:

Method

The determination was carried out by differential scanning calorimetry (DSC) using a procedure designed to be compatible with Method A2 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.

Conclusion

The test item did not boil up to 400 °C (673 K) at 101.5 kPa by differential scanning calorimetry,

Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
GLP compliance:
yes
Type of method:
method according to Siwoloboff
Boiling pt.:
> 300 °C
Atm. press.:
102.06 kPa
Remarks on result:
other: Test substance was stable under the conditions of the test.

Approx. 3 minutes after the capillary containing the test substance was inserted into the oven at 305 °C, the plug of test substance moved less than approx. 5 mm in the capillary tube, and remained inside the oven (it did not migrate to a cooler region of the pipette outside the oven). The colour of the test substance did not change during the test, which was consistent with the test substance being thermally stable under the conditions of the test.

Endpoint:
boiling point
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: analogue substance
Justification for type of information:
Investigation of boiling point is not required because available data indicate that structural variation does not influence test results or adverse effect profile (see read-across and category justifications attached in Section 13).
Reason / purpose:
read-across source
Type of method:
differential scanning calorimetry
Key result
Boiling pt.:
> 400 °C
Atm. press.:
101.5 kPa
Decomposition:
no

Description of key information

The boiling point of the analogue test item was determined to be > 400 °C.


Key value for chemical safety assessment

Additional information

The analogue test item did not boil up to 400 °C (673 K) at 101.5 kPa by differential scanning calorimetry. This property shows a correlation between molecular weight / chain length and boiling point. Measured boiling points for methyl esters of fatty acids prove this correlation. Fatty acid esters of a molecular weight > 300 amu and aβ-hydrogen in the alcohol chain (≥ 3 C) have a boiling point > 300 °C and decompose before boilingThe justification for read-across is presented in Section 13 Assessment reports- Read-across justification.
