摘要
Processes for recovering and recycling oligomers and polymerization catalyst from aqueous waste streams generated during the production of polyalkylene ether glycols are provided. The processes utilize membranes; preferably reverse osmosis or nanofilter membranes. The processes can reduce waste and costs associated with the polymerization of polyalkylene ether glycols by recovery and recycling of glycols and catalysts
