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.
Measurement
Vapor Pressure at 100°F (Calculated): 0.0286 mm Hg
Description of key information
The vapour pressure of a commercial sample of dodecan-1-ol is 0.038 mBar (3.8 Pa) at 38°C. It is supported by a consistent and reliable measurement of 0.11 Pa at 25°C using a highly pure sample (Daubert and Danner, 1989).
Key value for chemical safety assessment
- Vapour pressure:
- 0.11 Pa
- at the temperature of:
- 25 °C
Additional information
The vapour pressure of 3.8 Pa at 38°C was determined for dodecan-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 consistent and reliable measurement of 0.11 Pa at 25°C using a highly pure sample (Daubert and Danner, 1989). A value of 0.0493 Pa at 25°C, taken from a reliable reference source (Boublik et al., 1984) is also available.
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.
