Phase diagram of pyrene with 2,3-7,8-dibenzpyrene-1,6-quinone

The binary phase diagram of pyrene with 2,3-7,8-dibenzpyrene-1,6-quinone C 24 H 12 O 2 was studied experimentally in 20–400 °C temperature interval at 0–100% of pyrene. The melting point of C 24 H 12 O 2 was found to be 375 °C. The experimental data made it possible to estimate for the first time th...

Description
Summary:The binary phase diagram of pyrene with 2,3-7,8-dibenzpyrene-1,6-quinone C 24 H 12 O 2 was studied experimentally in 20–400 °C temperature interval at 0–100% of pyrene. The melting point of C 24 H 12 O 2 was found to be 375 °C. The experimental data made it possible to estimate for the first time the thermal effect of melting of C 24 H 12 O 2 . The additive method was used to estimate the thermodynamic characteristics of C 24 H 12 O 2 . Obtained data allow to perform the thermodynamic modeling and calculation of the phase diagram of the C 24 H 12 O 2 –C 16 H 10 system. Components form simple eutectic with coordinates of eutectic point: 94.70 mol% (91.58 mass%) of pyrene and 146.3 °C.
