Monte, M. J. S.[Manuel J. S.], Santos, L. M. N. B. F.[Luis M. N. B. F.], Fulem, M.[Michal], Fonseca, J. M. S.[Jose M.S.], Sousa, C. A. D.[Carlos A. D.]
A new static apparatus, capable of measuring vapor pressures in the range (0.4 to 133) Pa and in the temperature range (243 to 413) K, is fully described. The performance of the new apparatus was checked by measuring the vapor pressures of four compounds recommended as reference materials for the measurement of vapor pressures naphthalene, benzoic acid, benzophenone, and ferrocene. A recommended value for the enthalpy of sublimation of benzophenone, centscr g Hm 0 (298.15 K) ) (95.1 ( 1.9) kJamol-1, is suggested.
