Additional information

Information regarding vapour pressure of diacetone alcohol was sourced from three handbooks:

- From theCRC Handbook of Chemistry and Physics Ed. (2003) results a vapour pressure of 1.23 mm Hg (1.67 hPa) at 20°C is deducted using the Clausius Lapeyron Equation.

- NIOSH Pocket Guide to Chemical Hazards reports that the substance has a vapour pressure of 1 mm Hg at 68°F (1.35 hPa at 20°C).

Those 2 handbooks are known to contain peer-reviewed data of Klimisch-2 reliability

- The Sunshine, I. (ed.). of CRC Handbook of Analytical Toxicology. Cleveland: The Chemical Rubber Co., 1969., p. 637 reports a vapour pressure of 0.97 mm Hg (1.32 hPa) at 20°C
