Description of key information
GLP study according to EU testing method A.4(Effusion method: Vapor pressure balance).
Analytical Development Physical Chemistry, Schering AG, Berlin. Study report No. A03462 (ADP 2001_033), dated 2001-06-01.
Result: 5.7 E-10 Pa at 25°C (298K)
Key value for chemical safety assessment
Additional information
The temperature dependence of the vapour pressure was determined with the Knudsen effusion method using a vapour pressure balance in the temperature range 118 ‑ 148 °C.
The following vapour pressures were calculated for 20, 25 and 30 °C using a semilogarithmic linear regression based on the Antoin equation to be (with 95 %confidence intervall):
P20 = 2.0 · 10 -10 Pa (4.8 · 10 -11 to 8.7 · 10 -10 Pa)
P25 = 5.7 · 10 -10 Pa (1.5 · 10 -10 to 2.2 · 10 -9 Pa)
P30 = 1.6 · 10 -9 Pa (4.3 · 10 -10 to 5.6 · 10 -9 Pa)
