摘要：

In this study, the speeds of sound were measured in binary liquid mixtures of methyl oleate and either n-hexane or n-decane at temperature T = 303.15 K and pressures ranging from 0.1 MPa to 70 MPa. The data obtained from these measurements were used to calculate the excess speed of sound for these mixtures. The speed of sound molecular weight product, raised to a constant power ? was also calculated and represented as a function of molar percentage. This was done in order to determine a simple combining rule for representing the speed of sound of mixtures composed of n-alkanes and fatty acid alkyl esters.
