Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reaction mass:
79 degrees Celsius
351.44K (=78.3C)
Two separate TGD-approved handbooks agree that the substance has a boiling point of 82°C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
79 °C

Additional information

Company owned data from a study performed according to standard methods revealed a boiling point of 79 degrees C for the reaction mass which is in line with the values of the two constituents.


A small number of experimentally derived values are available, all consistently reporting very similar values and from reliable sources. The value from the key study was used as this was accepted as the critical study by the OECD chemicals.Other values are entirely consistent with this.


Information regarding boiling point of IPA was sourced from two separate handbooks. Merck Index: An Encyclopedia of Chemicals, Drugs, and Biologicals (14th Edition) and CRC Handbook of Chemistry and Physics (81st Ed), which are known to contain peer-reviewed data of Klimisch-2 reliability state that the substance boils at about 82°C at an atmospheric pressure of 1013 hPa (corresponding to 355.15 K at 101300 Pa).
