“…(12,18,41,(45)(46)(47)(48)(49)(50)(51)(52) The tests with benzoic acid and ferrocene indicate that the apparatus described in this paper, enables accurate determinations of the enthalpies of sublimation with very small amounts of sample compared to those used in our Knudsen effusion apparatus. (12)(13)(14) The standard molar enthalpy of sublimation of η 5 -bis-pentamethylcyclopentadyenyl iron, at T = 362.0 K, derived from the data in 30 Fe as a function of the temperature was also measured in this work, using a DSC 121 from Setaram and the procedure previously described.…”
