Reference
Endpoint:
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
Study period:
09.02.2006 - 09.02.2006
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Guideline study OECD 104, consistent with GLP.
Qualifier:
according to
Guideline:
OECD Guideline 104 (Vapour Pressure Curve)
Version / remarks:
adopted by the Council on 27 July1995
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.4 (Vapour Pressure)
Version / remarks:
Directive 92/69/EEC, Official Journal L 383 A 1992
Deviations:
no
Principles of method if other than guideline:
The vapour pressure is determined by measuring the boiling temperature of the substance at various specified pressures between roughly 10 to
approx. 10³ hPa. The apparatus consists of a tube with a boiling section (by electrical heating) in the lower part, a cooler in the middle part, and an
outlet to a pressure regulation system in the upper part. The thermometer is placed in the vapour above the surface of the liquid. The temperature of the vapour is measured as a function of the pressure.
GLP compliance:
no
Remarks:
consistent with GLP
Type of method:
dynamic method
Temp.:
20 °C
Vapour pressure:
0.01 hPa
Remarks on result:
other: The vapour pressure at 20 °C was calculated by mathematical extrapolation using the Antoine equation. Determined according to OECD guideline 104.

A portion of Ethyleneglycol dimethacrylate was given in a glass apparatus. The measurements started at the initial pressure of 15.2 hPa and at thermodynamic equilibrium. The pressure was increased stepwise.

Conclusions:
The vapour pressure of Ethyleneglycol dimethacrylate was determined according to OECD guideline 104 [adopted on 27 July 1995] and EU test
method A.4 [Directive 92/69/EEC, Official Journal L 383 A 1992] with the dynamic method.
The vapour pressure was: 0.01 hPa at 20°C.
Executive summary:

The vapour pressure of Ethyleneglycol dimethacrylate was determined according to OECD guideline 104 [adopted on 27 July 1995] and EU test method A.4 [Directive 92/69/EEC, Official Journal L 383 A 1992] with the dynamic method. The vapour pressure was: 0.01 hPa at 20°C.
