Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
107-07-3,chloroethanol,
The vapour pressure is from a calculated summary of literature data: 8.4 hPa at 20°C
Key value for chemical safety assessment
- Vapour pressure:
- 8.4 Pa
- at the temperature of:
- 20 °C
Additional information
The vapor pressure of 2-chloroethanol at 20°C was calculated using its Clausius-Clapeyron equation. The optimal fit for this equation was derived from 26 sets of data, measured vapour pressure, from several literature sources.
Clausius-Clapeyron equation
lnp=(ΔHvap /RT)+C
with
- p = vapor pressure in N/m2(or Pa)
- ΔHvap = heat of evaporation in J/mole
- R = gas constant (= 8.3142 J/mole.K)
- T = temperature in K (0°C = 273.15 K)
- C = constant
