Additional information

One reliable key study is available (Franke J, 2008).

The vapour pressure of TRIQUAT MONOMER was estimated on a theoretical basis from the vapour pressures of its components. The vapour pressures of the components at 25°C were either calculated or taken from the literature.

Based on the mole fractions of the single components, their respective vapour pressures and assuming ideal solution behaviour, the vapour pressure of TRIQUAT MONOMER was estimated to be 3062 Pa at 25°C.

Using Modified Watson Correlation with the experimental boiling point of 106.40°C, the vapour pressure of TRIQUAT MONOMER was estimated to be 3040 Pa at 25°C. This value supports the estimation based on the mole fraction of the single components.
