It has been proved that the general performance of aviation fuels can be improved with the addition of biofuels. To understand the fundamental physical properties of the blends, n-undecane, methyl decanoate, and n-butanol were chosen as model compounds to construct a mixed system. Densities (ρ) and viscosities (η) of the ternary system n-undecane + methyl decanoate + n-butanol and its corresponding binary systems n-undecane + methyl decanoate, n-undecane + n-butanol, and methyl decanoate + n-butanol were measured at different temperatures T = (293.15–333.15 K) and atmospheric pressure p = 0.1 MPa. The excess molar volumes (VmE) and the viscosity deviations (Δη) of the binary systems and the ternary system were correlated to the Redlich–Kister equation and four semi-empirical equations, respectively. The VmE values of the ternary system and binary systems are all positive over the entire concentration range at each experimental temperature, while their Δη values are all negative. The experimental results can provide reliable data for the compatibility of biofuels and fossil fuels.

正十一烷 (1) + 癸酸甲酯 (2) + 正丁醇 (3) 和相应二元混合物的密度和粘度从 T = 293.15 到 333.15 K 和在大气压下

事实证明,添加生物燃料可以提高航空燃料的综合性能。为了了解共混物的基本物理性质,选择十一烷、癸酸甲酯和丁醇作为模型化合物来构建混合系统。十一烷+癸酸甲酯+丁醇三元体系及其对应的十一烷+癸酸甲酯、十一烷+丁醇、癸酸甲酯+丁醇二元体系的密度(ρ)和粘度(η)在不同温度下测量T= (293.15–333.15 K) 和大气压力p = 0.1 MPa。二元系统和三元系统的过量摩尔体积 ( V m E ) 和粘度偏差 (Δ η ) 分别与 Redlich-Kister 方程和四个半经验方程相关。三元体系和二元体系的V m E值在每个实验温度下在整个浓度范围内都为正,而它们的Δ η值都为负。实验结果可为生物燃料与化石燃料的相容性提供可靠数据。
