Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
The boiling point of 103.4 °C determined by differential scanning calorimetry is nevertheless the boiling point of water influenced by the solvated aluminium nitrate and aluminium sulphate due to the effect of elevations of the boiling point.

Boiling point at 101 325 Pa:
103.4 °C

Additional information

The boiling point of the substance determined by differential scanning calorimetry in a test similar to OECD 103 is nevertheless the boiling point of water influenced by the solvated aluminium nitrate and aluminium sulphate due to the effect of elevations of the boiling point. The inorganic salts are assumed to have a very low vapour pressure. A decomposition temperature of 135 °C is given in literature for aluminium nitrate nonahydrate.
