摘要

报告了（一氧化碳 + 乙烷）和（一氧化碳 + 丙烷）混合物在气体区域的声速数据，对于含有乙烷的混合物，一氧化碳的摩尔分数为 0.25、0.5 和 0.75，温度范围为 273.15 K 至 350 K；对于含有丙烷的混合物，成分 xCO = 0.5 和 0.75，温度范围为 T = (260 至 350)K。测量是通过一个球形声共振器进行的，其扩大的相对不确定性（k = 2）优于 106 分之 250。实验数据被拟合到一个病毒式方程中，得到的标准偏差在测量的不确定性范围内。最后，所有这些数据都与天然气行业用作参考的 GERG-2008 和 AGA92-DC 状态方程进行了比较。

Speed of sound measurements in (carbon monoxide + ethane) and (carbon monoxide + propane) gas mixtures at T = (260 to 350) K and up to 12 MPa

Speed of sound data are reported for (carbon monoxide + ethane) and (carbon monoxide + propane) mixtures in the gas region at mole fractions of carbon monoxide of 0.25, 0.5 and 0.75 in the temperature range from 273.15 K to 350 K for mixtures containing ethane, and compositions x_CO = 0.5 and 0.75 at T = (260 to 350) K for mixtures with propane. Measurements are performed by means of a spherical acoustic resonator with an expanded relative uncertainty (k = 2) better than 250 parts in 10⁶. Experimental data are fitted to a virial type equation, obtaining standard deviations within the uncertainty of the measurements, and the adiabatic coefficient as perfect gas is derived from this fitting. Finally, all these data are compared to GERG-2008 and AGA92-DC equations of state, which are used as reference in the gas industry.

期刊介绍： The Journal of Chemical Thermodynamics exists primarily for dissemination of significant new knowledge in experimental equilibrium thermodynamics and transport properties of chemical systems. The defining attributes of The Journal are the quality and relevance of the papers published. The Journal publishes work relating to gases, liquids, solids, polymers, mixtures, solutions and interfaces. Studies on systems with variability, such as biological or bio-based materials, gas hydrates, among others, will also be considered provided these are well characterized and reproducible where possible. Experimental methods should be described in sufficient detail to allow critical assessment of the accuracy claimed. Authors are encouraged to provide physical or chemical interpretations of the results. Articles can contain modelling sections providing representations of data or molecular insights into the properties or transformations studied. Theoretical papers on chemical thermodynamics using molecular theory or modelling are also considered. The Journal welcomes review articles in the field of chemical thermodynamics but prospective authors should first consult one of the Editors concerning the suitability of the proposed review. Contributions of a routine nature or reporting on uncharacterised materials are not accepted.
