%X The gas-liquid critical temperatures, Tcm, of some mixtures of the electron donors, triethylamine, diethyl ether and diisopropyl ether with n-alkanes, benzene and hexafluorobenzene are reported. By using the van der Waals one-fluid model, an interaction energy parameter, &#958;, has been calculated for each mixture from the values of T&#176;m. The values of &#958; for the n-alkane+electron donors are fairly close to unity, indicating that, as would be expected, there are no strong specific interactions between the unlike molecules. The values of ( for the electron donors with benzene give no definite indication of specific interactions. On the other hand, values of &#958; for the electron donors with hexafluorobenzene indicate a specific interaction between the unlike molecules. These conclusions are discussed in relation to those reached from a consideration of other thermodynamic data.
