三种脂肪酸乙酯声速的实验测量与理论估算
Measurement and prediction of speed of sound of three FAEEs
摘要
Abstract
Biodiesels are regarded as the promising additives for fossil fuels, and fatty acid ethyl esters (FAEEs) are the main components of biodiesels. In order to obtain their speed of sound data, the speed of sound of three FAEEs were measured in this work using Brillouin light scattering method at temperatures from 293.15 K to 473.15 K and pressure of 0.1 MPa. The correlation for the speed of sound was also fitted as the function of temperature. The AAD was 0.13% for ethyl hexanoate, 0.11% for ethyl cinnamate and 0.08% for ethyl caprylate. The experimental data were also used to assess the predictive ability of Wada’s model and Auerbach’s model. It was shown that the former performed better than the latter one for the prediction of speed of sound of FAEEs.关键词
