ResumoChristou, G., Morrow, T., Sadus, R.J. and Young, C.L., 1986. Phase behaviour of fluoro-carbon and hydrocarbon mixtures: interpretation of type II and type III behaviour in terms of a ‘hard-sphere + attractive force’ equation of state. Fluid Phase Equilibria, 25: 263–272. Experimental measurements of the upper critical solution temperature of octadecafluorooctane + n-alkanes are reported. These measurements and those discussed by Schneider (1983) on the phase behaviour of tetrafluoromethane + alkanes are compared with results obtained from the one-fluid model using a ‘hard sphere + attractive term’ equation of state. Interaction parameters, ξ, obtained from the comparison together with values from the literature on other fluorocarbon + hydrocarbon mixtures show trends which are briefly discussed.
