乙醇胺乳酸盐离子液体吸收SO2过程中的物理化学性质
Physicochemical properties of ethanolamine lactate during SO2 absorption
摘要
Abstract
Densities and viscosities of ethanolamine lactate ([MEA]L) + H2O mixtures with different compositions were determined at temperatures from 303.15 to 333.15 K. Densities of [MEA]L + H2O decrease with the increase of temperature. Viscosities of [MEA]L + H2O decrease dramatically with the increase of temperature and the water content. Excess molar volumes (VE) and viscosities deviations (Δη) of the binary mixtures were calculated by the experimental data. The result shows that the values ofVEandΔη for the binary mixtures are negative over the whole composition range and temperature from 303.15 to 333.15 K. The negative of excess properties indicates a strong interaction between the ionic liquid and water. Densities and viscosities of [MEA]L with different water contents after SO2 absorption were also determined. The result shows that the densities and viscosities of [MEA]L + H2O after SO2 absorption decrease slightly. Besides, the Jouyban-Acree model was used to correlate the densities and viscosities of binary mixtures with respect to the mixture composition and temperature simultaneously.关键词
