Abstract (EN): The Knudsen mass-loss effusion technique was used to measure the vapour pressure as a function of temperature for four crystalline ß-diketones. From the temperature dependence of the vapour pressure, the standard molar enthalpies of sublimation ¿g crH°m(Tm) at the mean temperature Tm of the experimental temperature range were derived, and the standard molar enthalpies of sublimation, at temperature 298.15 K, were calculated: {A figure is presented}.
