Description of key information

Based on the formula provided in the Kirk-Othmer Encyclopedia of Chemical Technology, the vapour pressure of 1,1-dichloroethene is 66340 Pa at 293 K

Key value for chemical safety assessment

Vapour pressure:
66 340 Pa
at the temperature of:
20 °C

Additional information

All datasources provided comparable values for the vapour pressure of 1,1 -dichloroethene. Because the value provided by the Kirk-Othmer Kirk-Othmer Encyclopedia of Chemical Technology was derived from a formula (logPkPa= 6.1070 -1104.29 (T+237.697)) which was established covering a broader vapour pressure range, this value (at 20°C) was selected as the key parameter.
