Abstract: Experimental thermal conductivity values have been obtained in the region of the solid/liquid phase change for C24H50 (n-tetracozane) a representative of the n-alkanes at the atmospheric pressure and the temperature range of 312.85-325.16 k and temperature logs for mixtures of n-alkanes (paraffin) from C19H40 (nnonadecane) to C35H72 (pentatriacontane) during melting (296.60-359.59 k) and crystallizing (317.25-349.45 k) using the transient hot wire method. Transition temperatures have been determined: solid state/solid state (triclinic-rhombic transformation) at 315.65 k, solid state/solid state (rhombic-hexagonal transformation) at 316.95 k and solid state/liquid at 322.34 k.
