Abstract The total vapor pressure of liquid mixtures of xenon and diborane has been measured at 161.40 K (the triple point of xenon) and at 182.34 K (the triple point of dinitrogen oxide), as a function of composition. The liquid densities were also measured at 182.34 K. The mixtures show positive deviations from Raoult s law. Both the excess molar Gibbs energy (G(m)(E)) and the excess molar volume (V-m(E)) are positive. For the equimolar mixture G(m)(E) = 118.8 J.mol(-1) at 161.40 K, G(m)(F) = 91.7 J.mol(-1) at 182.34 K and V-m(F) = 0.248 cm(3).mol(-1) at 182.34 K. The estimated value of the excess molar enthalpy (H-m(E)) was found to be 328 J.mol(-1). The results were interpreted using the Deiters equation of state. This is the first thermodynamic study of the xenon + diborane system.
