The vapour pressure of the substance was determined
according to OECD Guideline
104 (vapour pressure), adopted on 23 March 2006. Isolation
of the substance from the commercial product in a degree of purity that
would allow the determination of its vapour pressure by experimental
means is technically not possible. Therefore the vapour pressure of the
substance was determined according to the Estimation Method (modified
Watson correlation) described in the Annex to OECD Guideline 104.
only experimental data required is the normal boiling point. No
boiling point could be determined for the substance. Instead
decomposition started at 220 °C. This temperature was considered to be
the lowest possible boiling temperature. The
vapour pressure obtained by calculation is 1.87 x 10E-6 atm (= 0.189 Pa)
at 20 °C.
The vapour pressure calculated for the substance is 0.189 Pa (20 °C)
