- Conclusions:
- Under the test conditions, amides, C12-18(even-numbered) and C18(unsatd.), N-hydroxyethyl shows an area of melting temperatures between 17 and 79°C (melting of crystalline parts).
- Executive summary:
The melting temperature of the amides, C12-18 (even-numbered) and C18-unsatd., N-hydroxyethyl was determined in accordance with the OECD Guideline 102 and EU Method A.1.
The practical test was performed based on the in-house test procedure VTA(S) 31X93001.02: "Melting temperature determination (Tm) of solid and liquid substances by means of DSC.
Under the test conditions, amides, C12 -18 (even-numbered) and C18-unsatd., N-hydroxyethyl shows an area of melting temperatures between 17 and 79°C (melting of crystalline parts).
The cooling run shows a crystallisation at 68°C.
Reference
The cooling run shows a crystallisation at 68°C.
Description of key information
The melting point was determined according to OECD Guideline 102 and EU Method A.1 (Kintrup , 2010a).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 17 °C
