Description of key information

Three different data sources report three different values of melting point. Since no details on test methods are given, it is not possible to evaluate the reliability of the results therefore the references were disregarded.
As conclusion, the melting point of HCFC 122a is unknown.

Key value for chemical safety assessment

Additional information

Three different data sources report three different values of melting point for HCFC 122a:

  • - 80 °C (Ministry of the Health of USSR)
  • - 19.9 °C (Yaws' Handbook of Thermodynamic and Physical Properties of Chemical Compounds)
  • - 173 °C (Solvay Safety Data Sheet)

Since no details on test methods are given, it is not possible to evaluate the reliability of the results and therefore all the references were disregarded.

As conclusion, the melting point of HCFC 122a is unknown.
