摘要

脂肪酸乙酯（FAEEs）是生物柴油中的重要成分，为了获取生物柴油组分的物性参数，利用布里渊散射法，分别沿0.1、2、4和6 MPa四条等压线，覆盖温度范围为298.15~508.15 K，测量了癸酸乙酯的液相音速。为方便工程应用，依据实验数据，给出了癸酸乙酯音速与温度和压力的关联式。在实验

范围内，实验值与关联式计算值的相对偏差绝对平均值为0.28%。常压下的实验数据也被用来评估Wada模型，结果表明Wada模型适用于预测癸酸乙酯常压下的音速。

Abstract

Ethyl decanoate

as a member of fatty acid ethyl esters (FAEEs)

is one of the main component of biodiesels. In order to obtain the thermophysical properties for the components of the biodiesels

this paper measured the the speed of sound in ethyl decanoate in the temperature range from 298.15 K to 508.15 K along four isobaric lines at

= (0.1

4 and 6) MPa by the Brillouin light scattering (BLS) method. The correlation for the speed of sound as a function of temperature and pressure is presented based on the experimental data

which provides convenience for engineering applications. The absolute average of relative deviation between the experimental data and the calculated results is 0.28% in the experimental

region. Besides

the experimental data of the speed of sound at atmosphere pressure were also used to assess the predictive ability of Wada’s model and the result shows that Wada’s model can be used to predict the speed of sound at atmosphere pressure for ethyl decanoate within a certain temperature range.
