Endpoint:
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
Study period:
13 March - 15 May, 2007
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
Study has been performed according to OECD and/or EU guidelines and according to GLP principles.
Qualifier:
according to
Guideline:
OECD Guideline 104 (Vapour Pressure Curve)
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.4 (Vapour Pressure)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Type of method:
effusion method: by loss of weight or by trapping vaporisate
Key result
Temp.:
20 °C
Vapour pressure:
3.88 Pa
Conclusions:
The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of Ditetrahydrofurylpropane. The vapour pressure of the test substance at 20°C (293K) was 3.88 Pa = 2.91 x 10^-2 mm Hg.
