Process for dehalogenation of contaminated waste materials

摘要

An improved method for detoxifying waste materials contaminated with halogenated hydrocarbons is disclosed. The method achieves dehalogenation of such halogenated hydrocarbons in a manner as efficient as previous methods, but at a considerably lower cost. The economic advantages of the present invention arise from the use of lower temperatures and/or smaller quantities of reagents, which in turn is made possible by the discovery of a surprisingly superior reagent, 2-methoxyethanol, and superior catalysts, the crown ethers, which allow reagents other than 2-methoxyethanol to function very efficiently in dehalogenation reactions.
