Description of key information

The vapour pressure of TS-ED 532 was determined to 4.8x10-8 Pa at 20 °C and 1.1x10-7 Pa at 25 °C. 

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
20 °C

Additional information

The vapour pressure of TS-ED 532 was determined using the gas saturation method. The average vapour pressure of TS-ED 532 at 123.6 °C, 133.9 °C and 144.0 °C was measured directly at the test temperature and was determined to 1.4x10-2 Pa, 3.8x10-2 Pa and 8.1x10-2 Pa, respectively.

Extrapolation of the vapour pressure based upon the simpliified Clausius-Clapeyron equation resulted in vapour pressures of

4.8x10-8 Pa at 20 °C and 1x10-7 Pa at 25 °C.
