Description of key information
According to Yaws Handbook of Physical Properties for Hydrocarbons and Chemicals (Electronic Edition) perfluoromethyl vinyl ether (PMVE) at the pressure of 1 atm melts/freezes at -155.15°C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -155.15 °C
Additional information
Information regarding melting/freezing point of perfluoromethyl vinyl ether was sourced from Yaws Handbook of Physical Properties for Hydrocarbons and Chemicals (Electronic Edition), known to contain peer-reviewed data of Klimisch-2 reliability, which reports that the test substance freezes at -155.15°C at 1 atm.
Based on the information obtained from secondary sources such as Company SDS the substance has a melting/freezing point < - 130 °C. Altought the datum obtained from the secondary sources is considered of Klimisch-4 reliability, it is consistent with the value reported by Yaws Handbook of Physical Properties for Hydrocarbons and therefore considered a supporting information.
