Conditions:

Room Temp: N/A

Compiler:

W.E. Acree, Jr.

Methodology:

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.

Sample Information:
  1. Analytical grade, Katayama Chemicals, Japan, was used as received.
  2. Reagent grade, Katayama Chemicals, Japan, was used as received.
Measurement Errors:

Ambient temperature: T/K: precision ±0.3 (compiler). x1: ±0.02 (compiler).

System Components:
  1. Naphthalene, $\ce{ C10H8 }$; [91-20-3] NIST WebBook
  2. Pyrene, $\ce{ C16H10 }$; [129-00-0] NIST WebBook
Experimental Data

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.
