Abstract

Методът се използва при регенериране на n-метилморфолин-n-окис, n-метилморфолин, морфолин и при пречистване на отпадъчни води. С него се намаляват физическите и химическите загуби в производствения цикъл при повишена икономичност и не се замърсява околната среда. Разтворите се нагнетяват през полупропусклива мембрана в съоръжение за обратна осмоза при температура от 30 до 400с и налягане около 40 бара. Обогатените с n-метилморфолин и морфолин разтвори могат да се обработят по познати начини с цел превръщане на посочените съединения в n-метилморфолин-n-окис. Съгласно метода при преработката на целулозата, по-специално при метода с използване на n-метилморфолин-n-окис, получените вещества според степента на концентриране могат да се въвеждат обратно в производствения цикъл. 3 претенции, 1 фигура
