Notes:
Author reports formation of an incongruently melting 1:1 phenanthrene - 1,2,3,5-tetranitrobenzene compound, and a 2:3 phenanthrene - 1,2,3,5-tetranitrobenzene molecular compound having a melting point temperature of 398.2 K. Two eutectic points occur at x
1
= 0.120 and T/K = 388.2, and at x
1
= 0.822 and T/K = 352.2. A peritectic point occurs at x
1
= 0.615 and T/K = 388.2. Compiler: From a thermodynamic viewpoint, phase diagram is more in agreement with formation of a 1:1 molecular compound, with the existence of a peritectic point at x
1
= 0.615 and at T/K = 388.2 and a miscibility gap at higher temperature, with a monotectic point close to x
1
= 0.12 and T/K = 392, and an eutectic point at x
1
= 0.822 and T/K = 352.2.
