“…A key advantage of the Tait equation is its ability to provide excellent results not only for interpolating and fitting density data but also for derived properties such as isobaric expansion and isothermal compressibility. The authors have previously applied the Tait equation in their research, ,− and it is defined as ρ false( T , p false) = ρ 0 false( T false) 1 − C ln ( B ( T ) + p B ( T ) + 0.1 MPa ) where ρ 0 false( T false) = A 0 + A 1 T + A 2 T 2 + A 3 T 3 B ( T ) = B 0 + B 1 T + B 2 T 2 …”

The environmental imperative driving the search for alternative fuels has fostered the rise of biofuels from biomass, offering renewable solutions that curtail petroleum dependence and greenhouse gas emissions. Propanol, as a primary biofuel, serves as an oxygenated additive, enhancing combustion efficiency and mitigating air pollutants. Propanol's oxygen-rich composition enhances engine performance and diminishes emissions. Studies on alkoxyethanols-gasoline blends showcase significant reductions in toxic pollutants, underscoring the need for thermodynamic understanding to foster cleaner energy. This study presents high-temperature and high-pressure density data for the binary mixture of 1-propanol, an alcohol, and 2-(2-methoxyethoxy)ethanol, an alkoxyethanol, covering temperatures ranging from 298.15 to 393.15 K and pressures from 0.1 to 140 MPa. The experimental density data were generated using a vibrating tube densitometer with an uncertainty of 0.7 × 10 −3 g cm −3 . Experimental density data were fitted by using the Tait-like equation, with low standard deviations. Also, the experimental measurements were correlated using PC-SAFT and Peng−Robinson equations of state. The derived properties, such as excess volume, isobaric thermal expansivity, and isothermal compressibility, were also calculated.

Hydrofluoroethers (HFEs) represent a new family of promising engineering fluids suitable for technical cleaning, cooling of electronic and magnetic devices or as admixtures in refrigerant blends. Here we report accurate data for the liquid density at 0.1\,MPa and temperatures from $273.15\,\mathrm{K}$ to $343.15\,\mathrm{K}$ for a series of five HFEs; namely HFE-7000, HFE-7100, HFE-7200, HFE-7300, and HFE-7500. A highly sensitive vibrating tube densimeter with a borosilicate glass U-tube calibrated according to the procedure by Prokopov\'{a} et al. [J. Chem. Thermodyn. 173 (2022) 106855] provided density data with an expanded uncertainty ($k=2$) of $0.13\,\mathrm{kg\cdot m^{-3}}$. Influences such as sample degassing, water content or sample temperature before its dosing into the densimeter are discussed. Thanks to the high sensitivity of the used densimeter, an unexpected shift in the density of different HFE-7100 and HFE-7200 liquid samples was detected. Unlike other HFEs, HFE-7100 and HFE-7200 are mixtures of two hardly separable isomers, which were so far considered having identical thermophysical properties. Utilizing nuclear magnetic resonance spectroscopy, the ratio of \textit{n}-isomer and \textit{iso}-isomer was inspected for various liquid samples. In the range of \textit{iso}-isomer mole fraction from 0.61 to 0.77, the new measurements revealed density differences of more than $5\,\mathrm{kg\cdot m^{-3}}$ in case of HFE-7100 and of about $3\,\mathrm{kg\cdot m^{-3}}$ in case of HFE-7200. Consequently, for some applications the properties of different HFE isomers cannot be considered identical. The Rackett-type correlation for the saturated liquid density was fitted using the new and the literature data.
