No information on the primary source of this
data or the methods used is available. However, this information is
taken from a reliable government source and is therefore considered to
be suitable for use as a key study.
The vapour pressure of DCPD is 1.4 mmHg at 20°C ( 186.651 Pa).
The Pocket Guide
presents key information and data
from the US Department of Health and Human Services and, as such, is a
reliable governmental source of information. It is considered a suitable
key study source for this endpoint (NIOSH 2005). This is supported by
data from the WHO ICSC (2005) which gives a vapour pressure of
180 Pa at 20°C. No information on the primary source of the data or the
methods used is available. However, this information is taken from a
reliable peer reviewed database and so can be considered reliable and
suitable for use for this endpoint.
The vapour pressure results are presented
for high purity (solid) DCPD but as some of the data were generated at
temperatures above the melting point, DCPD would be in liquid form. No
information is available on the vapour pressure of commercial (liquid)
DCPD but this is expected to be very similar to the high purity DCPD in
its melted (liquid) form.
