Density and phase transition study of the liquid crystal compound 50.16

摘要

Density and phase transition study for a liquid crystalline compound (50.16) is reported in this paper. This liquid crystalline compound as it is highly skewed in alkyl chain length. We experimentally measured the phase transition temperatures for the compound using a polarizing optical microscopy and differential scanning calorimeter. The densities of this liquid crystalline compound across all its phases as a function of temperature were measured using a capillary type dilatometer. The densities of the liquid crystals were calculated by correcting for the expansion of the glass capillary tube. These methods were found to be highly suitable for the calculation the phase transition and density of liquid crystalline with respect to temperature. The density data was used to calculate several parameters that provide an understanding of the phase behavior in such skewed liquid crystalline compounds.
