2, 2, 3, 3, 4, 4, 4-Heptafluoro-1-Butanol and 2, 2, 3, 3, 4, 4, 4-Heptafluorobutyl Acetate: Physicochemical, Thermophysical, and Spectral Data

New physicochemical data for 2, 2, 3, 3, 4, 4, 4-heptafluoro-1-butanol (≥ 0.998 mass fr.) and 2, 2, 3, 3, 4, 4, 4-heptafluorobutyl acetate (≥ 0.994 mass fr.) are presented. The dependences of the saturated vapor pressure of 2, 2, 3, 3, 4, 4, 4-heptafluoro-1-butanol and 2, 2, 3, 3, 4, 4, 4-heptafluorobutyl acetate on temperature were obtained. The coefficients of Antoine’s equation are calculated based on the experimental temperature–pressure dependence data. This article also presents data on the rheological properties (viscosity and apparent activation energy for the viscous flow) of the studied compounds. The dependencies of refractive index and excess volume (density) on temperature are studied. Fourier transform infrared spectroscopy spectra are also provided. The experimental data presented in this paper extend and complement the information presented in the scientific literature. These data are background information and a starting point for further research in engineering design of chemical processing equipment. In addition, the received data may support the development of property models of pure substances and systems containing them, such as phase behavior and the processes underlying it.
