Description of key information

The vapour pressure of chlorine was determined to be 6780 hPa at 20°C and 7787 hPa at 25°C.

Key value for chemical safety assessment

Vapour pressure:
6 780 hPa
at the temperature of:
20 °C

Additional information

The vapour pressure of chlorine was determined to be 6780 hPa at 20°C and 7787 hPa at 25°C.

The values were calculated with the Martin-Shin-Kapoor vapour pressure equitation. The average deviation between the predicted vapour pressure and the experimental values is 0.20 % with a standard deviation of 0.29 %.
