Abstract

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.
