Additional information

Three experimental results are available on the vapour pressure of tris(2 -butoxyethyl)-phosphate. Among them, two experimental data were found in the literature: a vapour pressure of 2.8 x 10^-5 Pa at 25°C was measured by Hinckley et al. (1990) and a vapour pressure of 2.4 x 10^-5 Pa by Small et al. (1947). A more recent study was performed in accordance with the EU Method A.4 and under GLP. The corresponding vapour pressure is 1.52 x 10^-5 Pa at 25°C (Howarth et al, 1995). This study was quoted by a reliability of (1) and was flagged as key study.
