Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2020
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:

- Key result
- Atm. press.:
- 1 013 kPa
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- not determinable
- Conclusions:
- No melting point between - 100 °C - 450 °C could be determined.
- Executive summary:
The thermal stability and decomposition point of diisobutyl phosphate was investigated by DTA/DSC corresponding to A.1., Council Regulations EC No 440/2008 and OECD 102 / OECD 113. The sample was weighed in a crucible made of aluminum, cooled down in a DTA/DSC-system to - 100 °C, tempered for 10 minutes and then heated up to 450 °C (heating rate 5 K/min) in air (1013 kPa). In comparison with an inert sample (empty crucible) the temperature difference and the heat effect was recorded.
No melting point could be detected.
