- Conclusions:
- The test item lmwitor 375 has a vapour pressure of ≤6.5 x 10^-4 atm (≤6.5 x 10^1 Pa; ≤6.5 x 10^-1 mbar) at 20 °C and of ≤4.7 x 10^-3 atm (≤4.8 x 10^2 Pa; ≤4.8 mbar) at 50 °C
- Executive summary:
The vapour pressure of the test substance was determined according to the Grain-Watson estimation method, in line with OECD test guideline 104.
The test item lmwitor 375 has a vapour pressure of ≤6.5 x 10^-4 atm (≤6.5 x 10^1 Pa; ≤6.5 x 10^-1 mbar) at 20 °C and of ≤4.7 x 10^-3 atm (≤4.8 x 10^2 Pa; ≤4.8 mbar) at 50 °C.
Reference
The experimentally determined vapour pressure of Imwitor 375 at 20 °C is not in the recommended range of 1 to 1000 mbar for DSC-measurements. Therefore a Grain-Watson estimation procedure in accordance with OECD 104 was used.
