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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to the literature, the test material decomposes at a temperature of 135 °C. However, the boiling point referred to in the literature may not be appropriate for this type of hydrated inorganic salt. Upon heating, the nonahydrate will initially release water promoting the aluminium nitrate to dissolve in its own hydrate water at 73.5 ⁰C. Further heating will then promote the release of water vapour. It is this loss of water vapour which is referred to in the literature and not the boiling point of aluminium nitrate. Differential thermal analysis (DTA) on the substance has also shown that one thermal event occur at 73.5 ⁰C. No further thermal events are observed below 200 ⁰C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 135 °C
Additional information
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.
