Abstract

Oppfinnelsen angår en fremgangsmåte for fremstilling av en nitrogen-inneholdende epihalohydrinpolymer som omfatter reaksjon av en nitrogen-inneholdende forløper valgt fra gruppen bestående av aminer, polyaminer, polyaminoamider, polyuretaner og blandinger derav med epihalohydrin for å danne en løsning av epihalohydrinpolymeren, fremgangsmåten omfatter et rensetrinn for å fjerne organiske urenheter fra den dannede løsningen av epihalohydrinpolymeren, rensetrinnet omfatter å kontakte løsningen av epihalohydrinpolymeren med et fluid under væske, superkritiske eller nær-superkritiske betingelser til å bevirke ekstraksjon av organiske urenheter fra løsningen av epihalohydrinpolymeren til fluidet, uttrekking av fluid anriket på organiske urenheter fra løsningen av epihalohydrinpolymeren, og separering av ekstraherte urenheter fra det uttrukkede fluidet, hvor fluidet omfatter en substans som ved atmosfærisk trykk og romtemperatur (ca. 25 °C) er gassholdig. Oppfinnelsen angår også en fremgangsmåte for rensing av en løsning av en nitrogen-inneholdende epihalohydrinpolymer. 1The invention relates to a process for the preparation of a nitrogen-containing epihalohydrin polymer comprising the reaction of a nitrogen-containing precursor selected from the group consisting of amines, polyamines, polyaminoamides, polyurethanes and mixtures thereof with epihalohydrin to form a solution of the epihalohydrin polymer. to remove organic impurities from the formed solution of the epihalohydrin polymer, the purification step comprises contacting the solution of the epihalohydrin polymer with a fluid under liquid, supercritical or near-supercritical conditions to effect extraction of organic impurities from the solution of the epihalohydrin polymer to the fluid, extraction of fluid rich organic impurities from the solution of the epihalohydrin polymer, and separation of extracted impurities from the extracted fluid, the fluid comprising a substance which is gaseous at atmospheric pressure and room temperature (about 25 ° C). The invention also relates to a process for purifying a solution of a nitrogen-containing epihalohydrin polymer. 1
