Key result
Temp.:
20 °C
Vapour pressure:
0 hPa
Temp.:
20 °C
Vapour pressure:
0 mm Hg
Conclusions:
The vapour pressure of thiourea is negligible.
Executive summary:

The vapour pressure of thiourea (CAS 62 -56 -6) as reported in the "BUA Stoffbericht 179" is 9.975E-08 hPa at 20 °C.

Description of key information

Due to the inherent substance structure of thiourea, it can be assumed that the vapour pressure of thiourea

can be neglected.

Key value for chemical safety assessment

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

Additional information

Due to the inherent substance structure of thiourea, it can be assumed that the vapour pressure of thiourea can be neglected. This assumption is supported by the values given in the technical report "BUA Stoffbericht 179" prepared by Beratergremium für umweltrelevante Altstoffe (BUA) der Gesellschaft Deutscher Chemiker, 1996. The vapour pressure of thiourea (CAS 62 -56 -6) as reported in the "BUA Stoffbericht 179" is 9.975E-08 hPa at 20 °C.
