ABSTRACT
Biodiesel is considered a feasible replacement for fossil fuels. Alcohols are 13 alternative biofuels, while also playing a role as additives to improve certain 14 properties of diesel and biodiesel. In this work, the thermal conductivity in the liquid 15 phase of binary mixtures of methyl caprate, usually the significant biodiesel 16 component with three higher alcohols (1-propanol, 1-butanol, and 1-pentanol), was 17 measured, with the temperature ranging from 287 K to 358 K at atmospheric pressure. 18 The total standard uncertainty of the experimental results was estimated at less than 19 2 % and the repeatability was better than +- 0.5 %. In addition, three correlations for 20 estimating the thermal conductivity of mixtures were fitted and improved, with the 21 average absolute relative deviation of the three correlations less than 0.30 %.
