Description of key information

Since the test item is a reaction mass of tetradecanoic anhydride and tetradecanoic acid, tetradecanoic anhydride and tetradecanoic acid were used for the read-across.

Calculation for vapour pressure with software tool MPBPWIN v1.43 for tetradecanoic anhydride : 0.000105 Pa (25 °C)

Calculation for vapour pressure with software tool MPBPWIN v1.43 for tetradecanoic acid: 0.000186 Pa (25 °C)

The vapour pressure of the test item could be included between these two values, therefore could be ca. 0.0001455 Pa (25 °C)

Key value for chemical safety assessment

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