Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)
GLP compliance:
yes (incl. QA statement)
Type of method:
differential scanning calorimetry
Decomposition:
yes
Decomp. temp.:
250 °C
Remarks on result:
other: No boiling point was observed ; decomposition and/or reaction occured at 250°C.

An exothermic effect was observed from approximately 250°C upwards in both the preliminary test and the main study. The effect was cause by reaction and/or decomposition of the test substance.

Below 250°C no boiling of the test substance was observed. After the experiment, a grey residue remained in the sample container.

Conclusions:
Reaction and/or decomposition of the test substance were observed at temperatures of >250°C. Boiling of the test substance was not observed below the temperature at which reaction and /or decompsition started. Based on this, the test substance has no boiling temperature.
Executive summary:

The boiling point of the substance was investigated in a study which was conducted in accordance with the standardised guideline EU Method A.2, and under GLP conditions.

Under the conditions of the study reaction and/or decomposition of the test substance were observed at temperatures of >250°C. Boiling of the test substance was not observed below the temperature at which reaction and /or decompsition started. Based on this, the test substance has no boiling temperature.

Description of key information

Reaction and/or decomposition of the test substance were observed at temperatures of >250°C. Boiling of the test substance was not observed below 250°C. Based on this, the test substance has no boiling temperature.

Key value for chemical safety assessment

Additional information

The boiling point of the substance was investigated in a study which was conducted in accordance with the standardised guideline EU Method A.2, and under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

Under the conditions of the study reaction and/or decomposition of the test substance were observed at temperatures of >250°C. Boiling of the test substance was not observed below the temperature at which reaction and /or decompsition started. Based on this, the test substance has no boiling temperature.
