Measurement
Vapor Pressure at 100°F (Calculated): 0.5734 mm Hg
The value at 25ºC is determined using the Antoine Equation by applying three standard coefficients for use in that equation, derived
by Boublik et al. from reliable raw data.Description of key information
The vapour pressure of a commercial octan-1-ol product is 0.7645 mBar (76.45 Pa) at 38°C. It is supported by a value of 10.1 Pa at 25°C, taken from a reliable reference source (Boublik et al., 1984). A consistent and reliable measurement of 10 Pa at 25°C using a highly pure sample is available (Daubert and Danner, 1989). These values are also supported by a predicted vapour pressure value of 11 Pa at 25°C using a validated QSAR estimation method. The quantified value at ambient temperature from Daubert and Danner is used in the chemical safety assesment.
Key value for chemical safety assessment
- Vapour pressure:
- 10 Pa
- at the temperature of:
- 25 °C
Additional information
A vapour pressure value of 0.7645 mBar (76.5 Pa) at 38°C was determined for octan-1-ol with the use of an isoteniscope method in accordance with ASTM D 2879. The result is considered to be reliable.
It is supported by a value of 10.1 Pa at 25°C, taken from a reliable reference source (Boublik et al., 1984). A consistent and reliable measurement of 10 Pa at 25°C using a highly pure sample is available (Daubert and Danner, 1989). These values are also supported by a predicted vapour pressure value of 11 Pa at 25°C using a validated QSAR estimation method.
In available secondary sources to which reliability could not be assigned, vapour pressure values of 0.031 hPa at 20°C, 1.3 hPa at 54°C and 2.2 hPa at 60.1°C were reported for the substance.
The quantified value at ambient temperature from Daubert and Danner is used in the chemical safety assesment.
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.
