Results and discussion

Boiling point
Key result
Atm. press.:
1 013.25 hPa
Decomposition:
yes
Remarks:
Reaction and/or decomposition was observed during and after melting of the test item.
Remarks on result:
other: Boiling of the test item was not observed below the temperature of decomposition and/or reaction, therefore the test item has no boiling temperature.

Any other information on results incl. tables

Boiling of the test item was not observed below the temperature of decomposition and/or reaction. Reaction and/or decomposition was observed during and after melting of the test item (melting temperature: 190.3°C). Based on this, the test item has no boiling temperature.

Applicant's summary and conclusion
