Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- supporting study
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- documentation insufficient for assessment
- Principles of method if other than guideline:
- Calculated
- GLP compliance:
- not specified
- H:
- 0.002 other: atm cm3/mole
- Atm. press.:
- 1 013 hPa
- Conclusions:
- Henry's law constant for DVB has been calculated to be 2.253E-3 atm cm3/mole. The compnents of DVB-55, -65, and -HP are concluded to be highly volatile from water.
- Executive summary:
Henry's law constant for DVB has been calculated to be 2.253E-3 atm cm3/mole.
Reference
Description of key information
The components of DVB-55, -65, and -HP have estimated Henry's Law Constants of approximately 0.002 atm*m3/mole (~200 Pa*m3/mole) and are thus expected to have high potential for volatilization from water.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 200
- at the temperature of:
- 20 °C
Additional information
Estimated Henry's Law Constant was generated using the group contribution method of U.S. EPA HENRYWIN software. The prediction indicates a Henry's Law Constant of 0.0022 atm*m3/mole at 25 °C. The ratio of measured vapour pressure to water solubility at 20°C gives an estimated Henry's Law Constant of 0.0018 atm*m3/mole (182 Pa*m3/mole). Therefore, the substances may be regarded as being highly volatile from water.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
