METHOD FOR PRODUCING POLYOXYALKYLENE GLYCOL ETHERS USING ALKOXYLATED ALKYLPHENOL-ALDEHYDE RESINS 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 is to react an alkoxide with an alkylation agent and includes to add water and a compound expressed by formula I (wherein R² expresses a 1-20C straight or branched alkyl radical; p expresses 1-75; X expresses a 1, 2-alkylene; k expresses 1-200) to a mixture comprising the formed alkoxide, the alkylation agent and the polyoxyalkylene glycol ether.;COPYRIGHT: (C)2008,JPO&INPIT
