Vapour pressure:

< 0 Pa

Key result

Test no.:

#2

Temp.:

50 °C

Vapour pressure:

< 0.001 Pa

Conclusions:

Based on the evaluation of data for other organic substances, the vapour pressure of the substance is determiend to be <0.00001 Pa at 25˚C and <0.001 Pa at 50˚C.

Executive summary:

Consideration of literature data on vapour pressure, molecular weight, boiling point and melting point of organic substances indicates that the vapour pressure of the test substance will be less than 0.0001 Pa at 20˚C and 0.001 Pa at 50˚C. Therefore, the value was not determined experimentally. Based on the evaluation of data for other organic substances, the vapour pressure of the substance is determiend to be <0.00001 Pa at 25˚C and <0.001 Pa at 50˚C (Macnab, 1987).
