Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From June 1998 to July 1998
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- GLP compliance:
- yes
- Type of method:
- thermal analysis
- Remarks:
- differential scanning calorimetry (DSC)
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- 140 °C
- Conclusions:
- Reactive Navy FC63805 has no melting point between 25–450 °C; exothermic decomposition starting at 140 °C was observed.
- Executive summary:
The determination of the melting point and the screening test for explosive properties by DSC, were carried out in closed glass pans and in aluminum pans with a hole.
No endothermic effect was observed prior to decomposition of the test substance in the range 135–240 °C, with a decomposition energy of 435 J/g. In an aluminum pan an exothermal effect was observable in the range of 30–160 °C. An exothermal decomposition was observed in the range 200–320 °C with a decomposition energy of 748 J/g.
The heat of decomposition was determined to be above 500 J/g.
Reference
Tests were carried out in closed glass pans and in aluminum pans with a hole. No endothermic effect was observed prior to decomposition of the test substance in the range 135–240 °C, with a decomposition energy of 435 J/g. In an aluminum pan an exothermal effect was observable in the range of 30–160 °C. An exothermal decomposition was observed in the range 200–320 °C with a decomposition energy of 748 J/g.
The heat of decomposition was determined to be above 500 J/g.
Description of key information
The melting point was examined following EU method A.1 in compliance with GLP. The test item decomposes before melting (starting at 140 °C).
Key value for chemical safety assessment
Additional information
The test item has no melting point between 25–450 °C, only exothermic decomposition beginning at 140 °C was observed.
