Description of key information

The vapour pressure of pure (Z)-octadec-9-enol is 0.002 Pa at 25°C. 

Key value for chemical safety assessment

Vapour pressure:
0.002 Pa
at the temperature of:
25 °C

Additional information

A vapour pressure value of 0.002 Pa at 25°C was determined for the substance with the use of a validated QSAR estimation method. The result is considered to be reliable.

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.
