Description of key information

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 Danner, 1989).

Key value for chemical safety assessment

Vapour pressure:
0.014 Pa

25 °C

Additional information

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 reliable.

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.
