“…The tie-lines on the triangular diagram do not have a consistent slope; however, other systems of this type have been noted in the literature (1). At the higher concentration of methanol, that is, above 30 wt.…”

sides. Figures 2, 3, and 4 illustrate the different etching characteristics of the primary PbTe and Sb. Figure 2 is a photomicrograph of an alloy which contains primary PbTe and eutectic; Figure 3 is of the eutectic composition, and Figure 4 shows primary Sb and eutectic.The solid solubility of Sb in PbTe is less than 0.1 wt. % and the solubility of PbTe in Sb is less than 0.5%. ACKNOWLEDGMENTWe thank the American Smelting and Refining Co. and the Bunker Hill Co. for the gifts of the lead and of the antimony, and the National Science Foundation for a grant which made this work possible.

“…Geometrical methods for interpolation and extrapolation of tie line data have been devised by Brancker et al (5), Sherwood (6), and Hand (7). While they are entirely graphical, these methods are useful for extrapolation.…”

no ternary azeotrope exists, as there is no maximum, minimum, or saddle-point pressure in this figure. Thus, tetrahydrofuran can be useful for breaking the ethyl acetate and cyclohexane azeotrope. The situation of equal ethyl acetate/cyclohexane relative volatility, which is the formation of a pseudoazeotrope, disappears when the tetrahydrofuran liquid-phase mole fraction exceeds 70 mol % as is also shown in this figure .
