Henry's Law constant
Administrative data
Link to relevant study record(s)
- Endpoint:
- Henry's law constant
- 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
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The Henry Law Constant was calculated using HENRYWIN v3.10.
- GLP compliance:
- not specified
- H:
- 3.9 Pa m³/mol
- Remarks on result:
- other: Temperature and atm. press. not reported; value based on bond estimation (value cited from: US-EPA 2004)
- H:
- 3.8 Pa m³/mol
- Remarks on result:
- other: Temperature and atm. press. not reported; value based on group estimation (value cited from: US-EPA 2004)
- Key result
- H:
- 1.4 Pa m³/mol
- Remarks on result:
- other: value calculated on basis of vapour pressure of 0.06 hPa (see IUCLID section 4.6) and calculated value of water solubility (0.6 g/L, see IUCLID section 4.8)
- Conclusions:
- The Henry Law Constant of 2-chlorobenzonitrile is reported to be between 1.4 and 3.9 Pa m³/mol.
- Executive summary:
The Henry Law Constant of 2-chlorobenzonitrile based on bond estimation and group estimation is 3.8 and 3.9 pa m³/mol, respectively (data source: US EPA). The Henry Law Constant based on vapour pressure of 0.06 hPa (see IUCLID section 4.6) and the calculated value of water solubility (0.6 g/L, see IUCLID section 4.8) is 1.4 Pa m³/mol.
These results indicate that 2-chlorobenzonotrile is only moderatly volatile from water.
