Description of key information
The boiling point of CuGUN was measured according to the OECD 103 guideline using differential scanning calorimetry (DSC) using a TA Instruments Q20 differential scanning calorimeter. The cell temperature ramped at 5°C/min to 500°C and the heat flow between the reference and sample is measured.
- An another test was realised according to OECD 103 guideline: the SIWOLOBOFF method which consist in heating the sample gradually in a tube which is immersed in a liquid bath. The increase of the bath temperature occurs at 1 °C/minute. Two determinations have been realized on a BUCHI type 535. No liquefaction was observed but a change of colour from blue to brown of the solid product occurred at about 211 °C. Then a strong decomposition was observed at 264 °C.
Key value for chemical safety assessment
Additional information
In the first study, the thermogram resulting from the analysis of CuGUN shows that the material does no display either a melting or boiling point, but instead goes directly to thermal decomposition beginning at 225°C.
In the second study, this result was confirmed: the boiling point of CuGUN was not reached before its total decomposition.
