Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results SIWOLOBOFF method

The sample started to melt at approx. 88°C and became a colourless liquid. No boiling was observed up to 250°C.

Therefore an additional run was performed in the DSC.

Results with DSC (Differential scanning calorimetry method)

   Endotherm 1 onset temp. (°C) Heat of melting (J. g-1)  Endotherm 2 onset temp. (°C)  Heat of melting (J.g-1) 

 Screening test

84.7  173.12  357.5  78.714 

An initial endotherm was observed with an onset of 84.7°C which correlates with the melting point of the test item.

A secondary endotherm was then observed at approx. 357.5°C. The endotherm was multi-peak and has therefore been attributed to decomposition. This is supported by the observation that at the conclusion of the test the sample was observed to have changed to a dark brown colour.

Conclusions:
SIWOLOBOFF method: melt at approx. 88°C and no boiling point was observed up to 250°C.
Differential scanning calorimetry (DSC): An intial endotherm was observed with an onset of 84.7 °C which correlates with the melting point of the test item.
Decomposition observed at 358°C

Description of key information

Decomposition observed at 358°C therefore no melting point can be determined.

Key value for chemical safety assessment
