Abstract

Isobaric vapor?liquid equilibrium at 101.3 kPa has been measured for the systems 1-pentanol + cyclohexane and 1-pentanol + n-hexane, at low alcohol mole fractions. These data were satisfactorily correlated with Wilson, NRTL, and UNIQUAC activity coefficient models to obtain the binary interaction parameters of both mixtures. With these parameters, an accurate knowledge of vapor?liquid equilibrium for both mixtures can be reached in a range of 1-pentanol mole fractions less than 0.1.

低醇组合物下1-戊醇+环己烷和1-戊醇+正己烷二元体系的等压汽液平衡

等压汽吗?测定了低醇摩尔分数下1-戊醇+环己烷和1-戊醇+正己烷体系在101.3 kPa时的液体平衡。这些数据与Wilson、NRTL和UNIQUAC活度系数模型进行了令人满意的相关，得到了两种混合物的二元相互作用参数。有了这些参数，就能准确了解水蒸气了吗?两种混合物在1-戊醇摩尔分数小于0.1的范围内均可达到液体平衡。

期刊介绍： The Journal of Chemical & Engineering Data is a monthly journal devoted to the publication of data obtained from both experiment and computation, which are viewed as complementary. It is the only American Chemical Society journal primarily concerned with articles containing data on the phase behavior and the physical, thermodynamic, and transport properties of well-defined materials, including complex mixtures of known compositions. While environmental and biological samples are of interest, their compositions must be known and reproducible. As a result, adsorption on natural product materials does not generally fit within the scope of Journal of Chemical & Engineering Data.
