Several values of Boiling Point for 1,2,2 -trichloro-1,2 -difluoroethano are reported.

Considering the different degrees of precision and the different pressure conditions, the values are generally consistent, with the exception of BP = 23 °C (Horvarth, A. L., 2001).

The most frequent one is Boiling Point = 72.5 °C, presumably observed at standard condition of pressure.

Conclusions:
Several values of Boiling Point for 1,1,2 -trichloro-1,2 -difluoroethano are reported.
The most frequent one is Boiling Point = 72.5 °C, which will be considered the key value.
Executive summary:

Several values of Boiling Point for 1,1,2 -trichloro-1,2 -difluoroethano are reported.

Taking into account the different degrees of precision and the different pressure conditions, the values are generally consistent.

The most frequent one is Boiling Point = 72.5 °C, presumably observed at standard condition of pressure, which will be considered the key value.

Description of key information

The Boiling Point of 1,1,2-dichloro-1,2-difluoroethane at the pressure of 760 Torr is 72.5 °C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
72.5 °C

Additional information

A reliable reference is reported, which provides a list of experimental values of boiling point under different conditions of pressure.

Considering the different degrees of precision and the different pressure conditions, the values are generally consistent.

The most frequent one is Boiling Point = 72.5 °C, presumably observed at standard condition of pressure, which will be considered the key value.
