Abstract:

Diethyl adipate is an important solvent and intermediate product in organic synthesis, used widely in domestic chemicals and food industry, such as spicery and plasticizing agent.Recently, it was found that oxygenated additives such as diethyl adipate could greatly improve fuel properties and reduce engine emissions, thus diethyl adipate is regarded as a good fuel additive and a potential alternative fuel in the future.However, few thermophysical properties of diethyl adipate are reported.In this study, the thermal conductivity of liquid diethyl adipate was measured at temperatures from 283 K to 383 K and pressures from 0.1 MPa to 30 MPa by the transient hot-wire technique with two anodized tantalum hot wires.The experimental data were correlated as a function of temperature and pressure.The absolute average deviation and the maximum deviation of the experimental results from the correlated equation were 0.14% and 0.43%, respectively.The uncertainty of the thermal conductivity was ±1.0%.
