Fast and Simultaneous Determination of Gas Diffusivities and Solubilities in Liquids Employing a Thin-Layer Cell Coupled to a Mass Spectrometer, Part II: Proof of Concept and Experimental Results

摘要: A new method for simultaneously determining gas diffusivities and solubilities in liquids was presented discussed detail Part I of this series. In part the series, measurement cell employed to determine oxygen 20 different dimethyl sulfoxide-based electrolytes. addition, a comparison values available literature made. From temperature dependence diffusivity between 40 °C an activation barrier 19 kJ mol-1 diffusion pure sulfoxide found. Moreover, qualitative agreement Jones-Dole viscosity coefficients on electrolyte concentration confirmed. The temperature-dependent solubility measurements revealed unexpected increase temperatures above 30 °C. While case alkali-perchlorates decreases with increasing concentration, pronounced salting-in effect lithium bis(trifluoromethane)sulfonimide observed.
