Abstract
Mass transport by an inert gas carrier was used to measure the temperature dependence of the octamethylporphyrin saturation vapor pressure: Inp = 50(/-2) - 32 300(+/- 1400)/T (T = 580-660) K) and to determine the thermodynam ic parameters of sublimation of this compound: DeltaH(subl) = 268 +/- 11 kJ /mol, DeltaS(subl)(circle) = 329 +/- 18 J/(mol K).
