M. author 2024-06 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. 0021-9568 https://hdl.handle.net/10259/11428 10.1021/ACS.JCED.4C00232 1520-5134 Alcohols Binary Mixtures Biofuels Fossil fuels Mixtures Measurement of Liquid Density of Mixtures of 1-Propanol + 2-(2-Methoxyethoxy)ethanol at Temperatures from 298.15 to 393.15 K and Pressures up to 140 MPa and Modeling Using PC-SAFT and Peng–Robinson Equations of State
