Abstract

Denne oppfinnelsen har som formål å tilveiebringe en fremgangsmåte for fremstilling av et smørsyreesterderivat med den generelle formel (2) ovenfor som er i stand til å fjerne forskjellige urene biprodukter hvis dannelse ikke kan unngås ved teknologien ifølge teknikkens stand, særlig forbindelsen med den generelle formel (1) ovenfor, på en effektiv måte. Denne oppfinnelsen angår en fremgangsmåte for fremstilling av et smørsyreesterderivat med den generelle formel (2) som innbefatter behandling av en blanding som inneholder en forbindelse med følgende generelle formel (1) med et addisjonsreagens i stand til å addere seg til nevnte etylenske binding og dermed omdanne nevnte forbindelse med den generelle formel (1) til et addisjonsprodukt som enkelt kan separeres fra nevnte smørsyreesterderivat med den generelle formel (2) og en fremgangsmåte for fremstilling av et smørsyresterderivat med den generelle formel (2) som innbefatter omsetning av en forbindelse med den generelle formel (3) med et salt av blåsyre ved en strømningsmetode.
