Slow evaporation vs slow solvent diffusion
Webb22 apr. 2024 · Choose some solvents to test which have a polarity that works from step (1). Now look at solvents vs vapor pressure. The lower the vapor pressure the slower the solvent will be to evaporate. Note that a mixture won't evaporate homogeneously. So with an acetone/glycerin mixture the acetone evaporates preferentially to the glycerin. Webb6 nov. 2012 · This technique involves the slow diffusion of one solvent into another. Two solvents are added to a vessel so that they form distinct layers (Fig. 2). A solvent in …
