Perfluoroorganic compounds (PFOC) are chemically inert that find ever increasing applications in biology and medicine as perfluorocarbon blood substitute emulsions and perfusion environment. The thermodynamic data of PFOC are scarce. The standard vaporization enthalpies, ∆vapH, of seven perfluorocarbons, namely cis- and trans- perfluorodecaline (PFD), perfluoro-N-(4-methylcyclohexyl) piperidine (PMCP), perfluorothreebutylamine (BAF-3), perfluorothreepropylamine (PAF-3), perfluorooctylbromide(PF-octylBr) и perfluorodibutyl ether (C4F9)2O were determined using Wadso and Calvet calorimeters. Using Sventoslavsky ebulliometer, temperature dependences of vapor pressure, ps, for these eight perfluoroorganic compounds were determined. The densities of their liquids were determined by picnometrically.
