PRODUCTION OF (POLY)OXYETHYLENE ALKYL ETHER ACETIC ACID

摘要

PURPOSE:To produce a highly pure (poly)oxyethylene alkyl ether acetic acid useful as a modifying agent for functional polymer materials and polymer materials used in living bodies in a process. CONSTITUTION:A (poly)oxyethylene alkyl ether compound is catalytically oxidized with oxygen or an oxygen-containing gas in the presence of a catalyst containing platinum and/or palladium as main components and further bismuth or lead as the second component under a pH of <=7 in an aqueous solution.
