Vapor pressures and vaporization enthalpies of 5-nonanone, linalool and 6-methyl-5-hepten-2-one. Data evaluation

• Vapor pressures for 5-nonanone, (±)-linalool and 6-methyl-5-hepten-2-one were measured.
• We used the static and the transpiration method.
• Available vapor pressures were collected and evaluated.
• Consistent data were treated together and reliable vaporization enthalpies were derived.
• Some commonly used predicting schemes were tested with the evaluated results.

Vapor pressures and vaporization enthalpies for 5-nonanone, linalool and 6-methyl-5-hepten-2-one seem to be in disarray. Temperature dependences of vapor pressures for these pure compounds were measured by using the static and the transpiration techniques. Molar standard enthalpies of vaporization at the reference temperature were derived. Available literature data on vapor pressures and vaporization enthalpies were collected and analyzed. The consistent data set for each compound was evaluated. Reliable thermodynamic parameters of vaporization were derived and used to test some commonly used predicting procedures.
