METHOD FOR PRODUCING POLYOXYALKYLENE GLYCOL ETHERS USING ALKOXYLATED OLIGO- OR POLYETHYLENEIMINES AS DEMULSIFIERS

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a polyoxyalkylene glycol ethers using an emulsion destroying agent.;SOLUTION: The method for producing the polyoxyalkylene glycol monoethers and/or diethers is to react an alkoxide with an alkylation agent and includes the addition of water, an oligoethylene imine or a polyethylene imine already alkoxylated with 1-100 2-4C alkylene oxide groups or a mixture of those alkylene oxide groups per one free NH group to a mixture comprising the formed alkoxide, the alkylation agent and the polyoxyalkylene glycol ether.;COPYRIGHT: (C)2008,JPO&INPIT
