Thermal conductivity of heavy, even-carbon number n-alkanes (C22 to C32)

The thermal conductivity of even carbon number n-alkanes from n-dodecane to n-dotriacontane (C22H46 to C32H66) was measured in both the liquid and solid phases, in the temperature range from 297.15 to 353.15 K at 0.1 MPa. To assure the purity and map the solid phase of the different samples during t...

Description
Summary:The thermal conductivity of even carbon number n-alkanes from n-dodecane to n-dotriacontane (C22H46 to C32H66) was measured in both the liquid and solid phases, in the temperature range from 297.15 to 353.15 K at 0.1 MPa. To assure the purity and map the solid phase of the different samples during the thermal conductivity measurements of the solid samples, the melting point, solid-solid transition temperature and their respective enthalpies were also evaluated. The thermal conductivity measurements for the liquid and solid samples were obtained within uncertainty levels better than 3% and 5%, respectively. To the best of our knowledge, this is the first report on the thermal conductivity of liquid n-hexacontane, n-octacontane, n-triacontane and n-dotriacontane, and, for solid samples, from n-docosane to n-dotriacontane.
