Abstract: Liquid toluene is a material used in industrial processes, and generally the thermal conductivity needs to be determined for efficient use. However, the thermal conductivity varies depending on high temperatures and other physical variables. The transient hot wire method has previously been used to obtain measurements of the thermal conductivity of toluene under multiple conditions to create reference data. This paper displays reference data correlation extending from 360 to 550 kelvin, where toluene is a saturated liquid, using two hot wire apparatus. The wire used are a bare 12.7 mm platinum wire and an anodized 25 mm tantalum wire. Uncertainties in these measurements are also discussed.
