Vapor pressure measurements on fluorene and methyl-fluorenes

Vapor pressures, molar enthalpies of sublimation, and molar enthalpies of vaporization of fluorene, 9-methyl-fluorene, and 1-methyl-fluorene have been determined by the transpiration method. Results were tested for internal consistency and compared with available literature data. New results help to resolve contradictions among a plethora of experimental data available for fluorene.
