So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Oliveira, Juliana A. S. A.; Morais, Victor M. F.; Monte, Manuel J. S. researched the compound: 2,5-Diphenyloxazole( cas:92-71-7 ).HPLC of Formula: 92-71-7.They published the article 《Thermodynamic properties of phase transitions of phenyl derivatives of maleic anhydride and oxazole》 about this compound( cas:92-71-7 ) in Journal of Chemical Thermodynamics. Keywords: maleic anhydride oxazole phenyl derivative phase transition thermodn property. We’ll tell you more about this compound (cas:92-71-7).
An exptl. study of the vapor pressures and related thermodn. properties of three Ph derivatives of maleic anhydride and oxazole is reported. The vapor pressures of the crystalline phase of these compounds were measured at different temperatures using the Knudsen mass-loss effusion method, enabling the determination of the standard (p° = 0.1 MPa) molar enthalpies, entropies and Gibbs energies of sublimation. The enthalpies and temperatures of fusion were determined from DSC experiments Quantum chem. calculations were used to calculate gas-phase isobaric heat capacities and absolute entropies.
This literature about this compound(92-71-7)HPLC of Formula: 92-71-7has given us a lot of inspiration, and I hope that the research on this compound(2,5-Diphenyloxazole) can be further advanced. Maybe we can get more compounds in a similar way.
