Abstract

Методът включва отделяне на аминооксиди, по-специално на n-метилморфолин от воден разтвор, по-специално от отпадъчни води, които се получават при преработката на целулоза, като разтворите влизат в контакт с катионобменна смола, чиито свързващи групи се състоят от карбоксилни групи. След това заредената катионобменна смола се промива и аминооксидите се обработват с воден разтвор на слаба киселина с рка стойност, по-голяма от 3,0, като елуент. 4 претенцииThe method involves the separation of amine oxides, in particular n-methylmorpholine, from an aqueous solution, in particular from waste water, which is obtained in the processing of cellulose, the solutions coming into contact with a cation exchange resin, the binding groups of which consist of carboxyl groups. The loaded cation exchange resin is then washed and the amine oxides are treated with an aqueous solution of a weak acid with an rka value greater than 3.0 as eluent. 4 claims
