The Separation of Solvent and Dissolved Substances: Methods for Precipitation

  • Gerd Brunner
Part of the Topics in Physical Chemistry book series (TOPPHYSCHEM, volume 4)


The separation of dissolved substances from the solvent in gas extraction is a necessary operation. Any suitable separation process can be employed, but processes are pRefserred which introduce no additional substances with only small changes in conditions of state. Additional fractionation of the extract during removal of the solvent from the extract, e.g., by stepwise reducing solvent power of the solvent, is a further aspect.
