Data on physical properties 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 on the review process was
documented 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 restrictionswas assigned
when using the authoritative secondary source.
Review of the collated information indicates
that, as gases, the butenes category members will partition primarily to
air. They have moderate solubility in water (based on measurement in a
closed system) and, as the butenes have a low boiling point (-6.9°C to
3.7°C) and their vapour pressures are above the limit of measurement
(i.e. 10^5 Pa), the substances have a high volatility.
The lower and upper explosion limits of the
butenes are 1.6 % - 10%, which results in a classification of category 1
flammable gas and the hazard statement 'extremely flammable gas'.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
