Atm. press.:
100.8 kPa
Decomposition:
yes
Decomp. temp.:
180 °C
Conclusions:
The water evaporation was observed between 40°C and 180°C. The thermal decomposition of the test substance was observed above temperature 180°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.Boiling temperature of the test substance, Acid Black 227, could not be determined because of thermal decomposition of the test substance.
Executive summary:

The boiling temperature of the test substance, Acid Black 227 was investigated. The Differential Scanning Calorimetry method was used.

The procedures used in the study were in accordance with:

Method A.2 – Boiling Temperature (1.6.6.2 Differential scanning calorimetry), Council Regulation (EC) No.440/2008, Published in O.J. L 142, 2008

OECD Test Guideline No 103, Boiling Point, Adopted July 27, 1995

The water evaporation was observed between 40°C and 180°C. The thermal decomposition of the test substance was observed above temperature 180°C.

Any peaks correspond to the boiling of the test substance was not observed to the temperature at which the thermal decomposition started.

Boiling temperature of the test substance, Acid Black 227, could not be determined because of thermal decomposition of the test substance.
