Description of key information
According to Hawleys condensed Chemical Dictionary, 14th Edition, the substance 5 -methylhexan 2 -one (MIAK) has been reported to have a freezing point of -73.9 °C at a pressure of 1 atm (101,325 Pa).
According to Yaw's Handbbook of Physical Properties of Hydrocarbons and Chemicals, the substance 5 -methylhexan-2 -one (MIAK) has been reported to have a freezing point of -73.9 °C at a pressure of 1 atm (101,325 Pa).
Furthermore, the melting point of the substance was predicted with the QSAR model MPBPWIN v1.44 (EpiSuite 4.11). The selected melting point (mean of Adapted Joback Method and Gold and Ogle Method) was determined to be -54.26 °C.
As the key value the value derived of Hawleys condensed Chemical Dictionary, 14th Edition is taken: -73.9 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -73.9 °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.
