Figure 8.

Suggested phase diagram at T=15 °C. The Ld-So 2-phase region is enclosed by three straight green lines and contains our IV and V tie-line fragments; the two open green circles at zero Chol show the coexistence compositions of Mitsui³⁰. The Ld-Lo 2-phase region is enclosed by one straight and one curved line and it contains our I, II and III tie-line fragments; the open red circles show the coexistence compositions of VSKG¹⁸. The Lo-So 2-phase region is enclosed by two straight and one curved blue lines; the open blue circles at zero DOPC show the coexistence compositions of Vist and Davis³⁴. The yellow point suggests the location of an upper consulate (critical) point and we found only one D-spacing for the composition of the black diamond.
