Endpoint:
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
Study period:
April 2010
Reliability:

Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
Qualifier:
according to
Guideline:
other: DIN-EN 13016-2

Key result
Temp.:
20 °C
Vapour pressure:
168 Pa
Remarks on result:
other: extrapolated value based on experimental results

The following regression equation was used to extrapolate to lower temperatures:

y = -2335.3x + 8.1906, R^2 = 0.9999

y: log P [hPa]

x: 1/T [°K]

This yields for 20°C a vapour pressure of 167.64 Pa.

The regression was based on the following experimental data:

Temperature Vapour pressure [hPa]
115 °C  150
120 °C  178
125 °C  211
130 °C  249
135 °C  293
140 °C  345
145 °C  403
150 °C  473
Conclusions:
Vapour pressure (DIN-EN 13016-2): 168 Pa at 20°C
Executive summary:

The vapour pressure was determined following the static method according to guideline DIN-EN 13016-2 ("MiniVap" device, Co. Grabner-Instruments).

Vapour pressure: 168 Pa at 20°C (extrapolated value).

All study results reported here were obtained using valid test methods and calibrated instruments. Standard operation procedures comply with the company’s Quality Management System certified by Deloitte Cert Umweltgutachter GmbH (Registration Numbers Z1 056-0308 and Z1 057 -0308) according to DIN EN ISO 9001 : 2008 and DIN EN ISO 14001 : 2009.
