Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The boiling point of isophorone diamine isobutyraldimine as determined by differential scanning calorimetry according to OECD TG 103 (1995) and EU Guideline A.2 (1992) is 302 °C at 1010.4 hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
302 °C

Additional information

The effect of the difference in pressure between normal (1013.25 hPa) and experiment (1010.4 hPa) is estimated to be below 1 °C. The value at 1013.25 hPa will be slightly above 302 °C. While a minor chemical reaction was observed at 128 °C, the vast majority of the substance remained stable up to the normal boiling point during the test. The reaction at 128°C can with high probability be assigned to an impurity.
