Thermodynamics of octamethylcyclotetrasiloxane mixtures

摘要: Vapour pressures of mixtures octamethylcyclotetrasiloxane + benzene and carbon tetrachloride have been measured at 25, 35, 45, 55, 60°C by a precision static vapour pressure method. For the first system excess entropy enthalpy are independent temperature. Excess volumes 25 also presented; for this they small negative. Results second will require calorimetric studies to finalize conclusions because uncertainties in virial coefficients tetrachloride. The were negative but larger magnitude.
