Adipic and Malonic Acid Aqueous Solutions: Surface Tensions and Saturation Vapor Pressures
Författare
Summary, in English
The surface tension of adipic aqueous solution has been measured as a function of temperature (T = 278-313 K) and adipic acid mole fraction (X = 0.000-0.003) using the Wilhelmy plate method. A parameterization fitted to these data is presented. The evaporation rates of binary water-malonic and water-adipic acid droplets have been measured with a TDMA-technique at different temperatures (T = 293-300 K) and relative humidities (58-80 %), and the saturation vapor pressures of subcooled liquid malonic and adipic acids have been derived from the data using a binary evaporation model.
The temperature dependence of the vapor pressures was obtained as least squares fits to the derived vapor pressures: ln (psat,l) [Pa] = 220.2389 – 22634.96/T [K] – 26.66767lnT [K] for malonic acid, and ln (psat,l) [Pa] = 140.6704 – 18230.97/T [K] – 15.48011lnT [K] for adipic acid.
