Specific details on test material used for the study:
O=[Cr](=O)=O
Temp.:
25 °C
Vapour pressure:
0 Pa
Temp.:
25 °C
Vapour pressure:
0 mm Hg
Conclusions:
The vapour pressure was determined to be 4.74E-9 Pa (Modified Grain Method). The measured melting point of 197°C was used for this calculation.
Executive summary:

The vapour pressure of the substance was predicted with the QSAR model MPBPWIN v1.43 (EpiSuite 4.1). The vapour pressure was determined to be 4.74E-9 Pa (Modified Grain Method). The measured melting point of 197°C was used for this calculation.
