Abstract

Foreliggende oppfinnelse angår en fremgangsmåte for fremstilling av trioksan og minst én komonomer for fremstilling av (ko)polymerer basert på trioksan, hvori, i et første trinn, formaldehyd med minst én komonomerreaktant omsettes i vandig løsning for å gi trioksan og komonomer, for å oppnå en reaksjonsblanding A1 som består av trioksan, komonomer, formaldehyd, og vann, med eller uten komonomerreaktant. I et andre trinn blir reaksjonsblandingen A1 destillert i et første destillasjonstrinn ved et første trykk for å oppnå en strøm B1 anriket i trioksan og komonomer og en strøm B2 som innbefatter i det vesentlige vann og formaldehyd, med eller uten komonomerreaktant. I et tredje trinn blir strøm B1 destillert i et andre destillasjonstrinn ved et trykk som er over trykket til det første destillasjonstrinnet for å oppnå en strøm C1 som innbefatter trioksan, komonomer og vann og en produktstrøm C2 som i det vesentlige består av komonomer og trioksan.
