Abstract

Data on the bulk viscosity coefficient of a binary system composed of alkanes of different molecular structure, namely, cyclic (cyclohexane) and linear (n-hexadecane) are presented for the range of pressure 0.1–98.0 MPa and temperature 293–393 K for solutions with concentrations of 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 mole fraction. The bulk viscosity coefficients were determined with an uncertainty of (8–10) % from experimental data on the absorption coefficient and sound velocity at the frequency of 28 MHz. The possibilities of the description of concentration dependences of the bulk viscosity coefficient

烃溶液在极端状态参数下的体积粘度。2。环状和线性烷烃（C6H12 - C16H34）的溶液

在压力为0.1 ~ 98.0 MPa，温度为293 ~ 393 K的条件下，对浓度为0.0、0.2、0.4、0.6、0.8和1.0摩尔分数的二元烷烃（环己烷和正十六烷）体系的体积粘度系数进行了研究。根据28mhz频率下吸声系数和声速的实验数据，确定了体积粘度系数，不确定度为（8 ~ 10）%。本文考虑了用Gruenberg-Nissan公式和作者提出的新的近似公式来描述体积粘度系数ηv的浓度依赖性的可能性。

期刊介绍： Fluid Phase Equilibria publishes high-quality papers dealing with experimental, theoretical, and applied research related to equilibrium and transport properties of fluids, solids, and interfaces. Subjects of interest include physical/phase and chemical equilibria; equilibrium and nonequilibrium thermophysical properties; fundamental thermodynamic relations; and stability. The systems central to the journal include pure substances and mixtures of organic and inorganic materials, including polymers, biochemicals, and surfactants with sufficient characterization of composition and purity for the results to be reproduced. Alloys are of interest only when thermodynamic studies are included, purely material studies will not be considered. In all cases, authors are expected to provide physical or chemical interpretations of the results. Experimental research can include measurements under all conditions of temperature, pressure, and composition, including critical and supercritical. Measurements are to be associated with systems and conditions of fundamental or applied interest, and may not be only a collection of routine data, such as physical property or solubility measurements at limited pressures and temperatures close to ambient, or surfactant studies focussed strictly on micellisation or micelle structure. Papers reporting common data must be accompanied by new physical insights and/or contemporary or new theory or techniques.
