Abstract
The thermal conductivity λ of phases liquid, I, II, III and the glassy crystal state of cyclohexanol has been measured using the transient hot-wire method at temperatures in the range 100–370K and at pressures up to 0·7 GPa. It was inferred from the observed temperature dependence of the thermal resistivity W (= λ-1) that molecular orientational disorder made a dominant contribution to the resistivity for the glassy crystal state under isobaric conditions. The same was found for plastic crystal phase I under isochoric conditions and also under isobaric conditions especially at the highest pressure. It was suggested that conformational disorder may make an important contribution to W for molecular crystal phases II and III.Keywords
