< 0.75

Conclusions:
A vapour pressure below 0.75 mm Hg at 20°C was determined for the test substance.
Executive summary:

The ASTM D2879 - 97 Standard Test Method for Vapour Pressure-Temperature Relationship and Initial Decomposition Temperature of Liquids by Isoteniscope was followed to determine the vapour pressure of Trans-hex-2-en-1-ol. The test substance was determined to have a vapour pressure at 20°C below 0.75 mm Hg.

Description of key information

The ASTM D2879 - 97 Standard Test Method for Vapour Pressure-Temperature Relationship and Initial Decomposition Temperature of Liquids by Isoteniscope was followed to determine the vapour pressure of Trans-hex-2-en-1-ol. The test substance was determined to have a vapour pressure at 20°C below 0.75 mm Hg (equivalent to 100 Pa).

Key value for chemical safety assessment

Vapour pressure:
100 Pa
at the temperature of:
20 °C
