Key value for chemical safety assessment

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

Additional information

The vapour pressure of the test substance was determined using a vapour pressure balance according to the procedure outlined in OECD 104. Temperature and pressure readings were taken between 63 - 73 deg. C. A total of six tests were performed. A calibration graph of Log Pa vs. 1/K was constructed to enable extrapolation of vapour pressure to 25 deg. C.

The test material showed negligible vapour pressure. The balance readings obtained for the test material were too low to give useful data for regression.An estimated vapour pressure was determined from a single reading at 63 deg. C (336.15 K)

The approx. vapour pressure of the test substance was estimated to be 1.506 x10-3 Pa at 25 deg. C
