Vapor Pressure at 100°F (Calculated):
0.0062 mm Hg
Tetradecanol was determined according ASTM D 2879. The
vapour pressure was determined to be 0.008 mBar at 100 °F (=38 °C).
The vapour pressure of a commercial sample
of tetradecan-1-ol is 0.8 Pa at 38°C. It is supported by a reliable
measurement of 0.014 Pa at 25°C using a highly pure sample (Daubert and
A vapour pressure of 0.008 mBar (0.8 Pa) at
38°C was determined for tetradecan-1-ol with the use of an isoteniscope
method in accordance with ASTM D2879. The result is considered to be
It is supported by a reliable measurement of
0.014 Pa at 25°C using a highly pure sample (Daubert and Danner, 1989).
A consistent and reliable vapour pressure value of 0.00293 Pa at 25°C is
available from a reliable reference source (Boublik et al., 1984). These
values are also supported by a predicted vapour pressure value of 0.0085
Pa at 25°C using a validated QSAR estimation method. In a secondary
source to which reliability could not be assigned, vapour pressure value
of 0.013 hPa at 20°C was reported for the substance.
The quantified value at ambient temperature
from Daubert and Danner is used in environmental modelling.
Discussion of trends in the Category
of C6-24 linear and essentially-linear aliphatic alcohols:
As chain length increases, vapour pressure
decreases. This is because molecular weight is higher and intermolecular
forces in the substance are all higher.
