Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
25 March 2002 to 19 April 2002
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.2 (Boiling Temperature)
Version / remarks:
Cited as Directive 92/69/EEC, A.2
GLP compliance:
yes
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
DSC was used to determine the boiling point.The sample was heated from 20°C to 450°C at a rate of 20°C/min.
Key result
Decomposition:
yes
Remarks:
no boiling point could be determined
Decomp. temp.:
> 300 °C
Remarks on result:
not determinable
No boiling point could be determined since the sample was observed to have decomposed.  The DSC trace shows that the sample decomposed at a  temperature above 300°C.
Conclusions:
No boiling point could be determined since the sample was observed to have decomposed.
Executive summary:

No boiling point could be determined since the sample was observed to have decomposed.

Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
Determined using DSC. The main test performed at a rate of 5 K/min - two tests were performed (250-400°C and 200-400°C). The results from the two tests (328.5°C and 328.9°C) were averaged.

Boiling pt.:
328.7 °C
Atm. press.:
ca. 101.325 kPa
Decomposition:
no

The boiling point was performed at a rate of 5 K/min - two tests were performed (250-400°C and 200-400°C). The results from the two tests (328.5°C and 328.9°C) were averaged.

The boiling point of BIT was determined to be 328.7°C.

The boiling point was performed at a rate of 5 K/min - two tests were performed (250-400°C and 200-400°C). The results from the two tests (328.5°C and 328.9°C) were averaged.
The boiling point of BIT was determined to be 328.7°C.
Executive summary:

The boiling point of BIT was determined to be 328.7°C.

Cited as Directive 92/69/EEC, A.2
GLP compliance:
yes
Type of method:
differential scanning calorimetry
Key result
Boiling pt.:
>= 339 - < 365 °C

The boiling point was determined using DSC by heating from 20°C to 400°C with a ramp of 10°C/min. Two determinations were made.

Boiling point range = 339°C to 365°C

Conclusions:
The boiling point was determined using DSC by heating from 20°C to 400°C with a ramp of 10°C/min. Two determinations were made.
Boiling point range = 339°C to 365°C
Executive summary:

Boiling point range = 339°C to 365°C

Description of key information

The boiling point was determined according to EU Method A.2 (Blake, 2002).

Key value for chemical safety assessment

Additional information

The substance decomposed above 300°C, therefore boiling point could not be determined.
