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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Data on physical properties of representative substances in this Category were obtained from a number of secondary sources. The data in these secondary sources are based on a critical evaluation of peer-reviewed data and the selected values are considered to be reliable and representative of the property under investigation. Information in the review process was documented in in the introduction of the source. The use of Klimisch codes (Klimisch et al., 1997), was extended to these secondary sources and a reliability code of (2)valid with restrictions was assigned when using the authoritative secondary source.
Review of the collated information indicates that as gases Category members will partition primarily to air. They have moderate solubility in water and low boiling point. As the boiling point of the representative substances (butene,isobutene, butane, Isobutane) ranges from -6.26 to 3.7°C, their vapour pressure will be above the limit of measurement ( i.e. 10^5Pa) but indicates that the substances will have a high volatility.
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.
