Study of Kinetics of Solid Phase Transition in Tetracosane C24H50 by High-Resolution Synchrotron X-Ray Powder Diffraction

摘要

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 C24H50 passes according to a heterogeneous mechanism in a narrow temperature range T 1 K in accordance with the theory of diffuse phase transitions.
