Tricosane-1,23-diol

N. Nakamura, K. Uno and Y. Ogawa

Abstract: In the title compound, C₂₃H₄₈O₂, one of the hydroxy groups adopts a gauche conformation with respect to the hydrocarbon skeleton, whereas the other hydroxy group adopts a trans conformation. The molecules form a layer structure similar to that found in the smectic A phase of liquid crystals. Inter- and intralayer hydrogen bonds are formed in the crystal. These features are similar to those of the homologues with an odd number of C atoms. The calculated density, however, deviates from that predicted by a relation between the density and the number of C atoms in alkane-,-diols with an odd number of C atoms.
