Original Measurements:
   Miyagishi, S.; Isomi, A.; Iwata, T.; Asakawa, T.; Nishida, M., Bull. Chem. Soc. Japan 1985, 58, 3643-3644.

 Variables:
   Temperature = N/A

 Prepared By:
   W.E. Acree, Jr.

 Experimental Remarks:
   Phase diagram, given in the original paper, shows that the system is a simple eutectic system. The eutectic point occurs at circa x2 = 0.22 and T/K = 335.7.

 Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   Differential scanning calorimeter and an analytical balance.
Binary mixtures were prepared by weight. Melting point temperatures and phase diagram determined using differential scanning calorimetric techniques.
