Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 30.05.2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)

- Key result
- Atm. press.:
- 98 kPa
- Decomposition:
- yes
- Decomp. temp.:
- 210 °C
- Remarks on result:
- other: not determinable
- Remarks:
- because of thermal degradation of test substance
- Conclusions:
- The water evaporation was observed between start temperature and 210°C. The main thermal decomposition of the test substance started at the temperature 210°C. Any peaks correspond to the melting or boiling of the test substance was not observed to the temperature at whitch the thermal decomposition started.Melting temperature temperature of the test substance, Direct blue 78, could not be determined because of thermal degradation of the test substance.
- Executive summary:
The melting temperature of the testsubstance, Direct blue 78 was investigated.The Differential Scanning Calorimetry method was used.
The procedures used in the study were in accordance with:
- Method A.1. Melting/Freezing temperature,Council Regulation (EC) No.440/2008, Published in O.J. L 142, 2008
- OECD Test Guideline No.102, Melting Point/Melting Range, Adopted July 27, 1995
Decomposition of the test substance was observed above 210°C, i.e. 483K. Melting of the test substance was not observed below the temperature at which decomposition started.
Melting temperature temperatureof the test substance, Direct blue 78, could not be determined because of thermal degradation of the test substance.
