Henry's Law constant
Administrative data
Link to relevant study record(s)
- Endpoint:
- Henry's law constant
- Type of information:
- (Q)SAR
- Adequacy of study:
- supporting study
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- results derived from a (Q)SAR model, with limited documentation / justification
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Estimation of the Henry's Law Constant (HLC) with the PC programme HENRY (v3.10, bond estimation method)
- GLP compliance:
- no
- H:
- 0.023 Pa m³/mol
- Temp.:
- 25 °C
- Atm. press.:
- 1 013 hPa
- Conclusions:
- The HLC of butane-1,3-diol was estimated to be 0.0233 Pa m³/mol at 25°C.
- Executive summary:
Based on a calculated HLC of 0.0233 Pa m³/mol (25 °C), 1,3 -butanediol is considered to have low potential for volatilization from water.
