Description of key information
Vapor pressure reported in handbooks: 116 hPa to 129 hPa (20°C)
Vapor pressure reported in authoritative databases: 124 hPa (20°C) to 133 hPa (21°C)
Key value for chemical safety assessment
- Vapour pressure:
- 129 hPa
- at the temperature of:
- 20 °C
Additional information
According to the data reported in handbooks and authoritative databases, Thionyl chloride exhibits a vapour pressure of 116 hPa to 129 hPa at 20°C. A vapour pressure of 129 hPa at 20°C was retained as key value on the basis of worst-case assumption. Besides, this value is consistent with available secondary data which report a vapour pressure of 116 hPa at 20°C and 119.3 hPa at 21°C for Thionyl chloride.
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.
