The measurement of thermal conductivity of alcohols from 0 to 80 ^∘C by the transient technique

Abstract

 The thermal conductivities of n- octanol, n-nonanol and n-decanol were measured in the temperature range from 0 to 80 ^∘C, by means of a computer-controlled transient calorimeter. The relations of the thermal conductivities of the three alcohols to temperature were derived as λ (mW/mK)=A−Bt, where A are 165.8, 167.8 and 169.4 mW/mK and B are 0.273, 0.287 and 0.293 mW/mK² for n-octanol, n-nonanol and n-decanol, respectively. The results obtained in this work is much better than the values reported in literature due to the calorimeter being considered to be able to eliminate the effects of convection and radiation.
