Abstract Densities and viscosities of ternary system (ethylcyclohexane + 1-butanol + ethyl octanoate) and three corresponding binary systems, (1-butanol + ethylcyclohexane), (1-butanol + ethyl octanoate), and (ethylcyclohexane + ethyl octanoate), were determined at 7 temperatures from 293.15 K to 323.15 K. For the ternary system and binary systems, the excess molar volumes (VmE) and viscosity deviations (Δη) of have been calculated. The VmE and Δη data were fitted to the Redlich − Kister equations. The VmE values for the investigated systems are all positive, and the Δη values are negative over the entire composition range. The density and viscosity data of blends and their corresponding excess properties or deviation may provide useful input data for thermodynamic or modelling studies.

（乙基环己烷 + 1-丁醇 + 辛酸乙酯）三元系统和相应二元系统在 T = (293.15–323.15) K 时的密度和粘度

摘要 测定了三元体系（乙基环己烷+1-丁醇+辛酸乙酯）和三个相应的二元体系（1-丁醇+乙基环己烷）、（1-丁醇+辛酸乙酯）和（乙基环己烷+辛酸乙酯）的密度和粘度在 293.15 K 至 323.15 K 的 7 个温度下。对于三元体系和二元体系，计算了 的过量摩尔体积 (VmE) 和粘度偏差 (Δη)。VmE 和 Δη 数据符合 Redlich - Kister 方程。所研究系统的 VmE 值都是正值，而 Δn 值在整个组成范围内都是负值。混合物的密度和粘度数据及其相应的过量特性或偏差可为热力学或建模研究提供有用的输入数据。
