Recommended Sublimation Pressures and Enthalpies for Biphenyl and trans-Stilbene
Original language description
Measurement of sublimation enthalpies, especially for low-volatility compounds, is challenging using traditional calorimetric methods, as well as indirect methods via the Clapeyron equation. To ensure consistency across laboratories, the International Confederation for Thermal Analysis and Calorimetry Working Group Thermochemistry established several reference materials in 1999. This work extends previous research by providing reliable sublimation pressures and enthalpies for biphenyl and trans-stilbene, proposed in 1999 as tertiary reference materials. Using STAT8 and STAT9 apparatuses, experiments were conducted to measure the sublimation and saturated liquid pressures for biphenyl (286-363 K) and trans-stilbene (323-433 K). These new data on vapor pressure were supplemented by ideal-gas heat capacities calculated by combining statistical thermodynamics and density functional theory calculations and heat capacity measurements using Tian-Calvet calorimetry. Calculated ideal-gas heat capacities and critically assessed experimental data on sublimation/saturated liquid pressure, condensed-phase heat capacities, fusion properties, and sublimation enthalpies were subsequently treated simultaneously to obtain a consistent description of the sublimation and vaporization thermodynamic properties. The results show that biphenyl and trans-stilbene meet the criteria for becoming primary reference materials for sublimation pressures and enthalpies. © 2025 Author(s).
