摘要
Recovery of an aprotic polar solvent from a saline aqueous solution of this solvent, by a process which consists in desalinating the said solution by electrodialysis and then distilling the desalinated solution. To avoid the precipitation of metal hydroxides during the electrodialysis, the brine is kept at an acidic pH.
