摘要：

The surface tension of adipic aqueous solutions was 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 parametrization fitted to these data is presented. The evaporation rates of binary water-malonic and water-adipic acid droplets were 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 were 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(P-sat,P-l) (Pa) = 220.2389 - 22634.96/T (K) - 26.66767 In T (K) for malonic acid and ln(P-sat,P-l) (Pa) = 140.6704 - 18230.97/T (K) - 15.48011 In T (K) for adipic acid.
