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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no

- Type of method:
- capillary method
- Key result
- Melting / freezing pt.:
- < -80 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- The melting point of the test item is < -20°C. Therefore, no further testing is required according to Annex VII of REACH.
- Executive summary:
No melting point or range could be detected. The melting point or range of the test item is < -80 °C (< 193.15 K). No further testing is required according to Annex VII of REACH as the melting point is < -20°C.
Reference
Pre-test: the test item was filled into glass vessels and stored at –80 and –20 °C.
Description of key information
The melting point of reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) is < -80 °C. As the melting point does not need to be determined below a lower limit of -20 °C (Annex VII of REACH), no main study was performed to determine the exact value.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -80 °C
Additional information
The melting point of reaction mass of 2,2'-oxybisbutane (DSBE), DIPE, SBA and 2-methylpropan-2-ol (TBA) was assessed according to OECD 102 resp. EU A.1 under GLP. In the study pre-test, the test item cooled to -80 °C was still liquid after six days of storage at this temperature. As the melting point does not need to be determined below a lower limit of -20 ° C (Annex VII of REACH), no main study was performed to determine the exact value.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
