Abstract

The saturation vapour pressure of {x BF₃ + (1-x)n-C₄H₁₀} has been measured at 195.49K. The system shows large positive deviations from Raoult's law and liquid-liquid immiscibility over a wide composition range whose limits have been estimated as 0.39±0.03<x>0.9785. The excess molar Gibbs energies (G_m^E) have been calculated as a function of composition from the vapour pressure data. For the hypothetical equimolar mixture G_m^E (x=0.5) = (703.9±29) Jmol^-1. The results were interpreted using the statistical associating fluid theory for potentials of variable range (SAFT-VR), as well as compared with those of related systems, such as (BF₃ + n-pentane) and (BF₃ + xenon).
