Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Additional information

The following boiling points are reported for aluminium triisopropylate in peer-reviewed handbooks taken forward in a weight of evidence approach:

CRC Handbook of Chemistry and Physics: 135 °C at 10 mm Hg

Hawley's condensed chemical dictionary, 13th revised edition: 138 - 148 °C at 10 mm Hg

The Merck Index: 135 °C (at 10 mm Hg), 131 °C (at 7.5 mm Hg), 125.5 °C (at 5.5 mm Hg), 113 °C (at 2.5 mm Hg), 106 °C (at 1.5 mm Hg) and 94 °C (at 0.5 mm Hg)

Ullmann's Encyclopedia of Industrial Chemistry: 125 - 130 °C at 533 Pa

Alkoxo and Aryloxo Derivatives of Metals: 135 °C (at 10 mm Hg), 132 °C (at 8.3 mm Hg), 131 °C (at 7.5 mm Hg), 124 °C (at 5.2 mm Hg), 122 °C (at 4.6 mm Hg), 118 °C (at 3.8 mm Hg), 111 °C (at 2.3 mm Hg) and 106 °C (at 1.5 mm Hg)

All values do match rather well and the most detailed ones are presented in Alkoxo and Aryloxo Derivatives of Metals.
