boiling point
Type of information:
experimental study
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
The boiling point is obtained from vapor-liquid equilibria measurements with a dynamic method, however, not enough details are provided on the apparatus to allow full comparison with OECD/EC guideline.
Reason / purpose:

Key result
Boiling pt.:
347.4 K
Remarks on result:
other: = 74.3 °C; experimental
Boiling pt.:
347.2 K
Remarks on result:
other: = 74.1 °C; litterature (Riddick 1986)

Above experimental result refers to 100% CF3CH2OH.

The physicochemical properties of pure components of this study are compared with litterature data.

Executive summary:

This publication deals with vapor-liquid equilibria of binary mixtures containing 2,2,2-trifluoroethanol, with ratio ranging from 0 to 1. Measurements were carried out at 102 kPa with a dynamic method, therefore the normal boiling point of 74.3°C for the pure substance can be derived; this result is also compared to the litterature value of 74.1°C.

Description of key information

Experimental result: 74.3°C

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
74.3 °C

Additional information

A published experimental study, conducted for vapor-liquid equilibrium measurements with a dynamic method, was considered reliable for the determination of the normal boiling point.

Literature data from one handbook and two databases provide consistent data. The Sax's handbook value was discarded, as considered inconsistent compared to the previous data (103 -105°C instead of 74 -77°C).
