Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
11 November 1998
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods
Qualifier:
according to guideline
Guideline:
other: ASTM E537-86
Deviations:
yes
Remarks:
As the substance decomposed at atmospheric pressure, an attempt was made to measure BP using a reduced pressure distillation technique
Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)
Version / remarks:
Directive 92/69/EEC - Reduced pressure distillatin technique
Deviations:
yes
Remarks:
As the substance decomposed at atmospheric pressure, an attempt was made to measure BP using a reduced pressure distillation technique
GLP compliance:
yes (incl. QA statement)
Type of method:
differential scanning calorimetry
Boiling pt.:
ca. 489 K
Atm. press.:
>= 5.1 - <= 8.1 kPa
Decomposition:
yes
Decomp. temp.:
ca. 489 K
Atm. press.:
>= 102.43 - <= 102.78 kPa
Decomposition:
yes
Decomp. temp.:
>= 453 - <= 633 K
Remarks on result:
not determinable
Remarks:
Substance was found to decompose between app. 453 and 633 K at 102.43 to 102.78 kPa

As the material decomposed, no value for the boiling temperature could be determined. BMS 214702 -01 was found to give the same thermographic profile when tested under nitrogen; this indicates that decomposition is probably thermal and not oxidative.

As BMS 214702 -01 decomposed at atmospheric pressure, an attempt was made to measure the boiling temperature using a reduced pressure distillation technique. At 5.1 to 8.1 kPa the test material began to boil; although distillation commenced at approximately 489 +/- 0.5 K, it was accompanied by decomposition and failed to complete.

Conclusions:
The substance was found to decompose between 453 and 633 K (180 C and 360 C) at 102.43 to 102.78kPa. As a result of this no value for boiling temperature could be determined at atmospheric pressure. Using a reduced pressure distillation technique, the substance was found to boil with decomposition from approximately 489 K (216 C) at 5.1 to 8.1 kPa.
Executive summary:

The substance was found to decompose between 453 and 633 K (180 C and 360 C) at 102.43 to 102.78kPa. As a result of this no value for boiling temperature could be determined at atmospheric pressure. Using a reduced pressure distillation technique, the substance was found to boil with decomposition from approximately 489 K (216 C) at 5.1 to 8.1 kPa.
