In this paper, a study of the thermal conductivities of a number of simple organic vapours at various pressures and temperatures was made and it was shown that the variation of conductivity with pressure is a function of gas imperfection.Abstract:
A study has been made of the thermal conductivities of a number of simple organic vapours at various pressures and temperatures. The measurements indicate that the variation of conductivity with pressure is a function of gas imperfection ; for substances with appreciable dipole interaction the effect is large, but for other substances where gas imperfection involves only van der Waals forces, the effect is much less. In all cases it is probable that the change in specific beat of the vapour with pressure is the main cause of the observed conductivity variation.read more

Initial Pressure Dependence of Thermal Conductivity and Viscosity
TL;DR: In this paper, the initial pressure dependence of thermal conductivity and viscosity of gases is considered to arise from molecular association and collisional transfer, and it is shown that at low temperatures molecular association is more important than collisional transfers.

Reference Correlation of the Thermal Conductivity of Methanol from the Triple Point to 660 K and up to 245 MPa
TL;DR: In this article, a theoretically based correlation was adopted in order to extend the temperature range of the experimental data for the dilute-gas thermal conductivity of methanol, which is applicable for the temperature ranges from the triple point to 660 K and pressures up to 245 MPa.

Molecular interactions and reorientational motion of neat acetone in the liquid state. 17O NMR chemical shifts and linewidths at variable temperature
TL;DR: The structure and dynamics of neat liquid acetone have been studied in the 181-325 K temperature range by 17O NMR as mentioned in this paper, and the chemical shift data are consistent with a monomer-dimer equilibrium.
