Thermal conductivity of solid CH2Cl2

Abstract

The isobaric thermal conductivity of solid CH2Cl2 was investigated by the linear-flow method under saturated vapor pressures in the temperature range from 80 K to the corresponding melting temperature and then recalculated for a constant density of the samples. The temperature dependence of isochoric thermal conductivity of solid CH2Cl2 is explained within a model in which the heat is transferred by phonons and above the phonon mobility edge by "diffusive" modes migrating randomly from site to site. The pressure dependence of the thermal conductivity of solid CH2Cl2 has been obtained.
