- Conclusions:
- The vapour pressure of the test item was estimated based on the Grain-Watson (GW) equation and found to be 4.7 E-10 Pa at 25°C.
- Executive summary:
The study was performed to estimate the vapour pressure of LZ 596 applying the QSAR models recommended by OECD Environment Monograph No. 67. The principle of the method is based on the modified Watson correlation. The following values were obtained:
- at 20°C: 1.88 E-10 Pa
- at 25°C: 4.70 E-10 Pa
- at 50°C: 2.94 E-08 Pa
