The crystal growth kinetics of two organic substances with low melting entropies — succinonitrile and cyclohexanol — was studied in the wide range of supercoolings. The values of kinetic coefficients which connect growth velocity and interface supercooling are equal to 0.17 – 0.72 m/(s · K) for succinonitrile and (1.6 – 2.0) · 10 −4 m/(s · K) for cyclohexanol. Viscosity of these substances was measured to compare the experimental data with theoretical dependences for continuous growth. It has been found that experimental kinetics of substances under study differs significantly from the expression of Wilson‐Frenkel type.
