Thermal conductivity is a very important transport property of fluids. In this work, the liquid thermal conductivity of five aliphatic esters (ethyl acetate, ethyl propionate, ethyl butyrate, ethyl pentanoate and ethyl hexanoate) were measured by transient hot-wire method at atmospheric pressure and with temperature range (249.13-348.46) K, (263.55-356.28) K, (268.57-363.52) K, (249.21-363.57) K, (254.29-383.37) K, respectively. It was estimated that the total relative standard uncertainty of the experimental results was smaller than 2% (in the 95% confidence level) and repeatability was better than +-0.5%. The liquid thermal conductivity results of the five esters were fitted as a polynomial function of temperature. The mean deviation and the maximum deviation of the fitted function from the experimental data of the five esters were 0.15% and 0.36% for ethyl acetate, 0.15% and 0.42% for ethyl propionate, 0.21% and -0.41% for ethyl butyrate, 0.21% and -0.42% for ethyl pentanoate, 0.32% and -0.69% for ethyl hexanoate, respectively.
