Abstract

Fremgangsmåte ved rensing av 3-klor-2-hydroksypropyltri-alkylammoniumklorid. En vandig oppslemming fremstilles som inneholder fra 70 til 98 vekt-% totale faststoffer, innbefattet kloridet og forurensninger i forbindelse med fremstillingen derav.Til denne oppslemming settes så en blandbar alkohol med fra 3 til 4 karbonatomer. Et fast filtrat samles og vaskes eventuelt med ytterligere alkohol og tørkes. Det faste filtrat er betydelig renere med hensyn til kloridet enn utgangsmaterialet.
