Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Remarks:
Reliable, company internal data.
Qualifier:
no guideline followed
Principles of method if other than guideline:
As the test substance are liquid at room temperature, evaporation is measured at supra-ambient temperatures using conventional differential scanning calorimetry (DSC).
GLP compliance:
not specified
Type of method:
differential scanning calorimetry
Key result
Remarks on result:
other: Poylmerization was observed before evaporation and this prevented proper determination of the evaporation point.
Conclusions:
Under the study conditions, the test substance exhibited polymerization and therefore the evaporation point was not determined.
Executive summary:

A study was conducted to determine the boiling point of test substance, DPHA using the differential scanning calorimeter (DSC). DPHA is a liquid at room temperature and hence evaporation is measured at supra-ambient temperatures using conventional DSC. Under the study conditions, the test substance exhibited polymerization and therefore the evaporation point was not determined (Herssens, 2010).

Description of key information

The boiling point of the test substance was determined using differential scanning calorimetry (DSC) (Herssens, 2010).

Key value for chemical safety assessment

Additional information

The substance polymerises before it can evaporate.
