Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Migrated phrase: estimated by calculation
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Remarks:
- The data source is considered reliable since it is a well review database of vapor pressure values and Antoine coefficients of over 9,995 compounds. The data contained in the database are both experimentally determined and estimated based on methods developed by the author and other noted experts.
- Principles of method if other than guideline:
- no data
- Type of method:
- other: not reported
- Temp.:
- 20 °C
- Vapour pressure:
- 130.71 hPa
- Remarks on result:
- other: Calculated according to the Antoine equation.
- Conclusions:
- According to the source, at the temperature of 20 °C, the vapour pressure of 1,1,2 -trichloro-1,2 –difluoroethane is 130.71 hPa.
- Executive summary:
The reference reports the Antoine coefficients for the calculation of the vapour pressure according to the formula:
log10 P(mmHg) = A - ( B / C + T(°C))
where:
A = 7.07039
B = 1256.05
C = 227.304
T = Temperature
According to the Antoine equation at the temperature of 20 °C 1,1,2 -trichloro-1,2 -difluoroethane assumes the vapour pressure of 98.04 mmHg (corresponding to 130.71 hPa).
Reference
The following Antoine coefficients are reported for the calculation of the Vapour pressure in temperature range
-14.2065 °C and 256.85 °C:
A = 7.07039
B = 1256.05
C = 227.304
Basing on the Antoine equation and on the reported coefficients, at the temperature of 20 °C 1,1,2 -trichloro-1,2 -difluoroethane assumes the vapour pressure of 98.04 mmHg (corresponding to 130.71 hPa).
Description of key information
The Vapour Pressure of 1,1,2-dichloro-1,2-difluoroethane at the temperature of 20 °C is 130.71 hPa.
