Description of key information

Vapour Pressure (EU-method A.4). The calculated vapour pressure is 2.74*10-6 Pa (25 °C)

Key value for chemical safety assessment

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

Additional information

The study does not need to be conducted if the melting point is above 300 °C. If the melting point is between 200 °C and 300 °C, a limit value based on measurement or a recognised calculation method is sufficient. "DOPO-OX-Ammonium" decomposed before melting. The decomposed test substance melted in the range of 311 to 330 °C. The vapour pressure of "DOPO-OX-Ammonium" was estimated to 2.74*10-6 Pa at 25 °C (atom/fragment contribution method using the software MPBPWIN).
