Vapour pressures and enthalpies of vaporization of a series of the ferrocene derivatives

The Kinetics of Ferrocene Volatilisation from an Ionic Liquid

“…substitute k for D in Equation (4) The value of 85 AE 2 kJmol À1 is similar to the previously reported activation energy of sublimation for solid Fc under a flow of N 2 gas (72.71 AE 0.24 kJ mol À1 ) [6] despite the obvious significant differences. No other comparable (solution to gas phase) values could be identified in the literature, the determi- …”

“…This value was chosen as it is higher than the flow rates of N 2 previously reported to be successful in monitoring the volatilisation of solid Fc (ca. 40-80 cm 3 min À1 ) [6] but did not disturb the surface of the ionic liquid. The CVs demonstrate the typical steady-state, mass-transportcontrolled waves expected at suitably slow scan rates at microelectrodes [26] for the simple one electron oxidation of Fc in [C 4 mpyrr][NTf 2 ].…”

“…Fc sublimes relatively quickly at atmospheric temperature and pressure, [6,7] as well as in vacuo. [4,8] Ionic liquids (ILs) have also found widespread applications, particularly with respect to typically possessing extremely low vapour pressures, [9] wide electrochemical windows and inherent conductivity.…”

The heat capacities and thermodynamic functions of some derivatives of ferrocene

“…DSC method was used for studying the heat capacities of four acetyl-and benzoyl-derivatives of ferrocene [4]. The saturated vapour pressures for three FD were measured by a transpiration method [5]. There are numerous data on the melting temperatures of BOF and BF determined by a simple capillary method [6][7][8][9][10].…”

Thermodynamics of the Phase Equilibriums of Some Organic Compounds

“…The temperature dependences of the vapor pressures for the ferrocene derivatives [FD] were determined by a transpiration method elaborated and fully described by Verevkin S.P. and coathers (Emel'yanenko et al, 2007). Here, only the main features of the method are given.…”
