ABSTRACT
Design of industrial devices frequently requires a wide and precise knowledge of the transport properties of all the fluids involved since efforts to reduce environmental impact often concentrate in the optimisation of their employment and in the use of new ones. The thermal conductivity is one of the most critical properties because organic compounds are widely required both for the production and the operation of the greater part of appliances.
In this paper an extension of a previously determined predictive method to new families of organic compounds is introduced: a simple equation relates the liquid thermal conductivity to the reduced temperature. It is effective in the range from the normal freezing point nearly to the critical point, though it does not take into account critical enhancement. Parameters are extracted from available thermophysical properties and evaluated for each family. Mean deviations are usually below 5% while typical maximum deviations are below 10% in the reduced temperature range 0.3 to 0.95.
