Abstract

In this paper, the 65 isobaric specific heat capacity (c_p) and 9 viscosity (η) data of 3,3,3-trifluoroprop-1-ene (R1243zf) were measured at temperatures from (230 to 293) K and pressure up to 8 MPa using a flow calorimeter and a vibrating-wire viscometer. The uncertainty of temperature, pressure, isobaric specific heat capacity and viscosity were evaluated to be less than 11 mK, 0.02 MPa, 1.0 % and 2.7 %, respectively. Three saturated liquid viscosity (η_s) data were obtained based on the extrapolation of the viscosity data. Empirical correlations were established based on the c_p and η_s data, the average absolute relative deviation for c_p and η_s are 0.5 % and 1.3 %, respectively.

温度为 (230 至 293) K、压力为 8 MPa 时液相中 3,3,3-三氟丙烯的等压比热容和粘度

本文使用流动热量计和振弦式粘度计测量了 3,3,3-三氟丙烯（R1243zf）在 230 至 293 K 温度和 8 MPa 压力下的 65 等压比热容（cp）和 9 粘度（η）数据。经评估，温度、压力、等压比热容和粘度的不确定性分别小于 11 mK、0.02 MPa、1.0 % 和 2.7 %。根据粘度数据的外推法获得了三个饱和液体粘度 (ηs) 数据。根据 cp 和 ηs 数据建立了经验相关性，cp 和 ηs 的平均绝对相对偏差分别为 0.5 % 和 1.3 %。

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.
