Abstract:
We have conducted x-ray diffraction, calorimetric and Brillouin-scattering experiments on n-butanol between 77 and 300 K, aiming to explore the physical nature of the so-called ‘glacial state’ previously found in n-butanol as well as in triphenyl phosphite. In addition to our structural and thermodynamic studies of the liquid–glass transition and of the stable crystal state in n-butanol, we have found that the metastable ‘glacial state’ that can be obtained in the temperature range 125–160 K is not a second amorphous state, but rather the result of a frustrated or aborted crystallization process that produces plenty of nanocrystallites embedded in a disordered matrix. The crystalline order of these nanocrystallites of the ‘glacial phase’ is exactly the same as that well observed in the fully ordered stable crystal into which it transforms by heating above 160 K.
