Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- from 30.10.1991 till 06.04.1992
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- method according to Siwoloboff
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: 746916/1991
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: room temperature, 20-24°C - Boiling pt.:
- 290 °C
- Atm. press.:
- 101.3 kPa
- Decomposition:
- yes
- Decomp. temp.:
- 150 °C
- Remarks on result:
- other: An exothermic decomposition is observed at about 150 °C. Therefore the boiling point was determined by extrapolation of the vapour pressure data.
- Conclusions:
- The boiling point of the substance could not be determinated by the Siwoloboff method. Extrapolated boiling point at 101.3 kPa: 290 °C
- Executive summary:
The test was carried out with DMPPA_701-402-5 according to OECD 103 guideline using Siwoloboff method. However, the boiling point of the substance could not be determined because the substance decomposes before the boiling point is reached. A yellow colouration of the substance is observed at about 190 °C and a regular string of bubbles cannot be observed until 190 °C. In the Differential Scanning Calorimeter (DSC) the start of an exothermic decomposition is observed at about 150 °C. Therefore, the boiling point was determined by extrapolation of the vapour pressure data from test no. FC 91/8T.VPC. A copy of the vapour pressure calculation data sheet is attached. Extrapolated boiling point at 101.3 kPa: 290 °C.

Description of key information
The boiling point of the substance could not be determined because the substance decomposes before the boiling point is reached. A yellow colouration of the substance is observed at about 190 °C and a regular string of bubbles cannot be observed until 190 °C. In the Differential Scanning Calorimeter (DSC) the start of an exothermic decomposition is observed at about 150 °C. Therefore, the boiling point was determined by extrapolation of the vapour pressure data from test no. FC 91/8T.VPC. A copy of the vapour pressure calculation data sheet is attached. Extrapolated boiling point at 101.3 kPa: 290 °C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 290 °C
