ABSTRACT:
A process is described for removing contaminants from a contaminant-laden solution of dialkyl ethers of polyethylene glycols (polyether solvent) by mixing the solution with an aqueous base solution. The mixture produces at least two liquid phases of different densities, which are then separated from each other. The lighter liquid phase is predominantly the polyether solvent while the heavier liquid phase is predominantly the aqueous base solution and the contaminants. The process is particularly useful in removing triethylene glycol and other glycol-based dehydration solvents.
