Phase Transitions in a Mixture of Tri- and Pentacosane Molecular Crystals

详细

Phase transitions (PTs) in a mixture of normal alkanes—tricosane (C₂₃H₄₈) and pentacosane (C₂₅H₅₂)—have been investigated by differential scanning calorimetry. Elimination of methodological errors makes it possible to obtain true values of the thermodynamic PT parameters and reveal their nature. Jumps of the specific heat have been comparatively analyzed based on the theory of diffuse first-order PTs.
