Additional information

A vapour pressure value of 12 hPa at 20 °C is nominated as the key study (Gmelins 1951) among the other secondary sources. This peer-reviewed chemical handbook is considered as a reliable source referencein which the original data sources are traceable.

Approximate values of 13 hPa at 20 °C are from secondary sources (Whitehead 1983, HSDB and Grayson & Eckroth, O'Neil 2006) which are not available for review and no further information is available. The reliabilities of these results are not assignable. A predictive method has also been reported (Millennium 2007) but no further details are available.
