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)
- Adequacy of study:
- supporting study
- Study period:
- no data
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- secondary literature
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- other: no guideline reported
- Principles of method if other than guideline:
- Estimated by calculation based on water solubility (136 g/L at 20 °C) and a vapour pressure of Ps = 9.975*10^-8 hPa.
- GLP compliance:
- no
- Key result
- H:
- 0 Pa m³/mol
- Temp.:
- 20 °C
- Conclusions:
- The Henry constant for thiourea was estimated by calculation: H = 5.58E-09 Pa m³/mol. Therefore, thiourea is considered to be non-volatile from aqueous solutions.
- Executive summary:
The Henry constant of thiourea was estimated by calculation based on the substance's water solubility (136 g/L at 20 °C) and a vapour pressure of Ps = 9.975*10^-8 hPa: H = 5.58E-09 Pa m³/mol. Therefore, thiourea is considered to be non-volatile from aqueous solutions.
