Process for the extractive isolation of ethylene glycol dialkyl ethers and ethylene glycol monoalkyl ethers from mixtures of these ethers

摘要

In this process which is based on a liquid-liquid extraction forming a hydrophilic phase taking up the monoethers and a hydrophobic phase taking up the diethers, the hydrophilic extractant used is water and the hydrophobic extractant used is a chlorinated hydrocarbon.
