Notes:
     Phase diagram suggests formation of a 1:1 naphthalene - 1,3,5-trinitrobenzene molecular compound having a melting point of circa T/K = 425.7. Two eutectic points occur at about x₁ = 0.11 and T/K = 387.3 and at x₁ = 0.95 and T/K = 351.2.

Method/Apparatus/Procedure:
   Binary mixtures prepared by weight. While the experimental details were not given in the paper, compiler speculates (based upon quantity of material used) that the sample was sealed in a glass container, temperature slowly varied, and the phase diagram determined by visually noting the temperature at which the last/first crystal of solid disappeared/appeared.

Source and Purity of Materials:
   (1) Purity and chemical source were not specified in paper.
   (2) Purity and chemical source were not specified in paper.

Estimated Errors:

   Temperature: T/K: precision ± 0.2 (compiler). x₁: ± 0.002 (compiler).
