Experiment and correlation of the thermophysical properties for binary and ternary liquid mixtures of three fatty acid ethyl esters and n-dodecane

In present study, surface light scattering (SLS) was used for the simultaneous determination of liquid surface tension and kinematic viscosity of the binary and ternary mixtures of three fatty acid ethyl esters (FAEEs) and n-dodecane. The SLS apparatus was firstly checked with n-dodecane and a good agreement between our data and those from literatures could be found. By utilizing this apparatus, both properties were investigated in the temperature ranges between (308 and 413) K. Additionally, the liquid density and refractive index were determined by a densimeter between (293 and 423) K and a refractometer from (278 to 358) K, respectively. The thermophysical property data obtained in this study were correlated as polynomial equations of temperature and mole fraction of the pure components. This work provided the crucial thermophysical properties and the corresponding models in connection with the application in the design and optimization of the injection system of internal combustion engine (ICE).
