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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Melting point of aluminium triisopropylate based on a weight of evidence approach is 119 °C at 1 atm
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 119 °C
Additional information
Whereas the CRC handbook of Chemistry and Physics and the Merck Index does report a melting point of 119 °C, Ullmann's Encyclopedia of Industrial Chemistry reports 118 °C at 1 atm. In Hawley's condensed chemical dictionary, 13th revised edition, the melting point is reported being between 128 and 132 °C which seems to be somewhat high (outlier). Therefore, the value of 119 °C is taken forward as melting point in this dossier.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
