Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

In the first can, a first transition is observed at 69°C probably due to the melting of the primary amides, followed by a second transition at 101°C for the secondary amides.

A second scan shows that another melting is present at 73 -76°C, that substitutes the tranistions of the first can and that most likely accounts for the imidazolines melting. These findings are supported by IR spectra that show different vibrations, for the first can C=O vibration for amides, for the second scan C=O for imidazolines.

Conclusions:
The substance was tested for melting point following OECD 102 (K-Cons, 2018). Under the experimental conditions three transitions are recorded at 69°C (primary amides), 101°C (secondary amides) and, in a second scan, between 73-76°C (imidazolines).
Executive summary:

The substance was tested for melting point following OECD 102 (K-Cons, 2018). Under the experimental conditions three transitions are recorded at 69°C (primary amides), 101°C (secondary amides) and, in a second scan, between 73-76°C (imidazolines).
