Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Justification for type of information:
- 2-ethylhexanol and pentane-2,4-dione are two main hydrolysis prodcuts of the target substance. Properties of the the two substance are used for read-across.
- Guideline:
- other: not specified.
- GLP compliance:
- not specified
- Type of method:
- other: not specified.
- Specific details on test material used for the study:
- 2-ethylhexanol and pentane-2,4-dione are two main hydrolysis products of the target substance. The properties of the two hydrolysis products are used for read-across.
- Key result
- Melting / freezing pt.:
- ca. -70 °C
- Atm. press.:
- ca. 1 atm
- Conclusions:
- the melting/freezing point of 2-ethylhexanol is -70°C according to literature.
Reference
Description of key information
Melting/freezing point of 2 -ethylhexanol, the hydrolysis prodcut is -70.0 according to literature.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -70 °C
Additional information
In a preliminary test in which the test substance was placed under -40°C and no freezing was observed. The melting point was therefore below -40°C.According to hydrolysis test results, the hydrolysis rate was estimated to be within several minutes. The hydrolysis products had been identified to be 2-ethylhexnol, acetylacetone and titanium dioxide. The melting point of 2-ethylhexanol was chosen for CSA.
