A study of solid phase transition kinetics in the tetracosane С$_{24}$Н$_{50}$ with the help of high resolution synchrotron X-ray powder diffraction

Using the small-angle synchrotron X-ray diffraction method at the research facility “BELOK” of the Kurchatov synchrotron radiation source at the NRC Kurchatov Institute, it was shown that the first-order solid phase transition in tetracosane С$_{24}$Н$_{50}$ passes according to a heterogeneous mechanism in a narrow temperature range $\Delta T\sim$ K in accordance with the theory of diffuse phase transitions.
