Abstract

Det beskrives en fremgangsmåte for fremstilling av cykliske estere ved omdan- nelse av hydroksykarboksylsyrer og deriva- ter av disse til de respektive cykliske estere. Slike cykliske estere, som inklu- derer laktid eller glykolid, er spesielt anvendbare ved fremstilling av polymerer som kan anvendes for å lage biologisk ned- brytbare materialer, så som biologisk ned- brytbare innpakningsmaterialer. Forskjel- lige fremgangsmåter for fremstilling av cykliske estere beskrives, inkludert reak- sjoner i flytende fase og i dampfase. Det beskrives også forskjellige fremgangsmåter for utvinning av cykliske estere fra pro- duktholdige strammer.
