Figure 1
Schematic three-component T–X phase diagram for 2,3-tetralindiol drawn primarily from the data of Lettré & Lerch (1952); schematic T–X diagrams for each pair of components are also shown. The temperatures given are the highest values for each phase (see Table 1). The area corresponding to the phase containing both the cis and trans isomers is darkened. The two-component diagrams for the cis and enantiomerically pure components have been simplified; Lettré & Lerch (1952) indicate (see their Fig. 3) that in the nominal 1:1 phase of cis and R,R- (or S,S-) trans isomers some of the trans molecules may be replaced by cis molecules. |
