Description of key information

Available data indicate a vapour pressure of 12 kPa at 20°C and 15.2 kPa at 25°C.

Key value for chemical safety assessment

Vapour pressure:
12 046 Pa
at the temperature of:
19.9 °C

Additional information

Data are available in a peer-reviewed handbook : 15.2 kPa at 25°C (CRC Handbook, 2009) and in a well described publication : 12046 Pa at 19.9°C and 14549 Pa at 24°C (Boublik, 1972). These values are in good agreement and thus are regarded as reliable.
