在（288.15,293.15,303.15和313.15）K和常压下，测量了碳酸二乙酯（DEC）与乙醇、1-丙醇、1-戊醇和1-辛醇的二元混合物在全摩尔分数下的密度和粘度。此外，在303.15 K时测定了二元混合物的过量摩尔焓。其他混合性质，如多余的摩尔体积，也得到了每个系统和温度。将组分粘度数据与几个特定方程相关联，以评估它们对这些体系的适用性。
Densities and viscosities of the binary mixtures of diethyl carbonate (DEC) with ethanol, 1-propanol, 1-pentanol, and 1-octanol were measured over the entire mole fraction at (288.15, 293.15, 303.15, and 313.15) K and normal atmospheric pressure. Moreover, the excess molar enthalpies for the present binary mixtures were determined at 303.15 K. Other mixing properties such as the excess molar volumes have been also obtained for each of the systems and temperatures. The composition–viscosity data were correlated with several specific equations to evaluate their suitability for these systems.
