Boiling pt.:
ca. 261 °C
Atm. press.:
101.3 kPa
Decomposition:
yes
Remarks:
(From 261°C the test item shows a boiling and/or thermal decomposition with evaporation of the decomposition components).
Decomp. temp.:
> 261 °C
Remarks on result:
other: The DSC measurements were confirmed by means of TGA measurements (no significant weight reduction below the main weight loss) under the same measuring conditions.

From 261°C the test item shows a boiling and/or thermal decomposition with evaporation of the decomposition components.

The DSC measurements were confirmed by means of TGA measurements (no significant weight reduction below the main weight loss) under the same measuring conditions.

Conclusions:
Under the test conditions, the amides, C12-18(even-numbered) and C18(unsatd.), N,N-bis(hydroxyethyl) shows a boiling point at ca. 261 °C.
Executive summary:

The boiling point of the the test substance was determined in accordance with the OECD Guideline 103 and EU Method A.2.

The practical test performance was based on the in-house test procedure VTA(S) 31X93002.02: "Boiling temperature determination (Tb) of solid and liquid substances by means of DSC.

Under the test conditions, the test substance showed a boiling point at ca. 261 °C (Kintrup, 2010).

Description of key information

The boiling point was determined according to OECD Guideline 103 and EU Method A.2 (Kintrup, 2010b).

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
261 °C
