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. |
