Experimental Studies on The Thermal Conductivity of Methyl Laurate Component of Biodiesel with Three Higher Alcohols Jing Fan, Shuangshuo Liu, Fenhong Song, Hongwei Li, Wenpeng Hong



Biodiesel has been considered as one of the feasible attempts to replace the fossil fuels. Alcohols always played a role as the additives to improve the certain properties of biodiesel. In this work, the thermal conductivity in the liquid phase of binary mixtures of methyl laurate usually the significant biodiesel component with three higher alcohols (1-propanol, 1- butanol and 1-pentanol) was measured with the teamperature ranging within 287 K to 358 K at atmospheric pressure. The total standard uncertainty of the experimental results was estimated to be less than 2 % and the repeatability was better than ± 0.5 %. The thermal conductivity data of binary mixtures were fitted as a function of temperature, and the average absolute relative deviation and the maximum absolute relative deviation between the experimental data and calculated results were 0.08 % and 0.23 % for methyl laurate/1-propanol, 0.09 % and 0.32 % for methyl laurate/1-butanol, 0.10 % and 0.31 % for methyl laurate/1-pentanol, respectively.
