Equation of state for C60 fullerene aqueous solutions

In the present work PVT data of the C60 fullerene aqueous solution (C60 FAS) were measured as a function of the concentration of C60 molecules using the variable cell method with metal bellows in the temperature range from 295 to 360 K at pressures from 0.1 to 103.2 MPa. On the liquid–vapor equilibrium line the density (ρ) of the C60 FAS was measured using the pycnometer method. As a result, numerical values for the isothermal modulus of elasticity (K T ), isobaric expansivity (α P ), isothermal deviation of entropy factor (TΔS), enthalpy (ΔH), and internal energy (ΔU) have been determined. Finally, an equation of state for the C60FAS was obtained for the first time.
