This system was studied only by Sokolov and Pochtakova (Ref. 1) who suggested the phase
diagram to be of the eutectic type, the invariant point occurring at 521 K (248 °C) and
Component I, however, forms liquid crystals. Therefore the temperature of 633 K (360 °C)
given in Ref. 1 should be identified with the clearing (and not the fusion) temperature
of this component, and compared with the Tclr(l) value (625.6~0.8 K) reported in
For the same component, three phase transition temperatures are quoted in Ref. 1 from
Ref. 2, i.e., 621, 546, and 481 K, the second of which can...
